'''P'''lay'''S'''tation '''ARC'''hive is a generic file container that uses an internal hierarchy of subfolders with defined access paths, and optional zlib or lzma per-file compression
'''P'''lay'''S'''tation '''ARC'''hive is a container that allows subfolders and per-file compression using zlib or lzma with 9 compression levels


 
===PSARC Tools===
The access paths are stored in a special file generated at build time called '''manifest''', It mimics a standard tree structure of folders/files but the root of the hierarchy is not defined, this way the contents of the psarc can be "mounted" by the system/game as part of his filesystem at any place and under any device letter/name
 
There are 3 different methods to generate this paths that defines how the .psarc contents are mounted by the system/game, this methods are enabled by the '''archive flags''' stored in the header, the system/game knows how to recreate the filesystem paths and mounts the .psarc contents by reading the '''archive flags''' that are needed to process the access paths in the '''manifest'''
 
 
 
The compression algorithms, the PS3 system, and the .psarc format, allows for 9 compression levels but in the practice only are used level 0 (no compression) or 9 (max compression used as the default compression level)
 
Compression level 9 for generic file types results as a compression ratio of around 50% of the original size, the final compression ratio can vary for different types of files, usually multimedia files (video, audio, etc) doesn't allow much compression because are already compressed originally (as example, max compression ratio for .BIK video and .MP3 audio doesn't reach 1% or 2%). For this reason is better not to compress multimedia files because the size reduction is ridiculous and read access times can be reduced (causing a delay/lag/freeze when trying to load the file)
 
Very small files (smaller than 100 bytes or so) as well as dummy files (0 bytes) doesn't admits compression because are so small that the compression algorithm is not able to reduce them, they will be stored without compression inside the .psarc archive even when is applied compression over them. When listing the contents of a .psarc with this kind of files will be displayed with a percentage of 100% and both his compressed and decompressed sizes the same value

*'''Relative''' (default, no flags)
**Default value when the .psarc is created from command line or an .xml and no special access paths modes are specified
**The paths in the '''manifest''' doesn't have an slash character at the start of every line, the system accesses the files exactly like if the .psarc was a folder itself
**e.g: '''Folder/File.bin"'''
**In the games that uses .psarc's without flags (like ''uncharted'' series or ''the last of us'') is possible to replace the psarc by a folder with the same name of the psarc and his contents decompressed inside
 
*'''Ignorecase''' flag
**Enabled by using the option '''--ignorecase''' in command line or '''ignorecase="true"''' in the .xml
**The paths in the '''manifest''' are case insensitive (doesnt matters wich characters are in capitals)
 
*'''Absolute''' flag
**Enabled by using the option '''--absolute''' in command line or '''absolute="true"''' in the .xml
**The paths in the '''manifest''' have an slash character at the start of every line, <!-- the .psarc contents are mounted directly in the root of the application space (under USRDIR)... this is hidden because is a bit speculative, im not so sure but this is what it looks -->
**e.g: '''/Folder/File.bin"'''

===Manifest===
Manifest is the first file inside the psarc filetable, doesn't appears as a file when using the '''--list''' command and doesn't have an assigned '''ID'''
 
In windows all the paths uses the slash "\" but when the psarc is created the paths are stored inside the manifest as "/". When making a '''--list''' command over a psarc the slashes will appear as "/"
 
To make things more generic all examples in wiki uses full PC paths, this allows to place the sources (files to create, or psarc to extract), targets (files to create, or psarc to extract), and psarc.exe in any path of the PC, using full paths makes needed the use of the "strip" option in all creation process to remove part of the PC path and device letter from the access paths stored in the '''manifest'''

'''Usage:'''
  PSARC [flag] <fileName>
'''Flags:'''
  -l            Creates a text file that lists the File ID, Size, and Name of every file in the archive.
  -e START END  Extracts files with the File ID specified by the range between START and END (inclusive).
  <blank>        Extracts all files.
 
*Examples:
**Extract all files from data.psarc :    PSARC data.psarc

====Performing actions with an XML list====
Is posible to automatize the '''create''' and '''extract''' actions by using an .xml
 
Using an xml is the most flexible way to use psarc.exe because has full support for all features of the tool (command line doesnt), some of the options of the tool are only available when using an xml, specially per-file attributes like: per-file compression (used by lot of games), or per-file extraction
 
To use an .xml is needed to prepare it based in this layout
{{Boxcode|title=This is the xml representation of the DTD layout containing all the elements and attributes availables together, for wiki purposes only|code=<syntaxhighlight lang=xml>
<psarc>
<create archive="" absolute="false" ignorecase="false" mergedups="false" stripall="false" blocksize="65536" jobs="" skipmissingfiles="false" format="psarc" overwrite="false">
<compression type="zlib" level="9" enabled="true" />
<strip regex="" />
<exclude regex="" wildcard="" />
<file wildcard="" regex="" path="" archivepath="" fromarchive="" compressed="true" skipifmissing="false" />
<directory path="" archivepath="" fromarchive="" compressed="true" skipifmissing="false" />

</create>
<extract archive="" to="" stripall="false" skipmissingfiles="false" overwrite="true">
<file archivepath="" skipifmissing="false" />
</extract>
</psarc>
</syntaxhighlight>}}
*The purpose of this XML is to use it as a base layout containing all, but is not possible to use it like that, is needed to delete the tags that are not needed for a specific case, the ones that are incompatibles with other tags, and is needed to add paths, etc...
*Some attributes appears as common in the DTD for "create" and "extract" but are not common, some of them has been deleted to avoid mistakes... but probably is needed to delete some more
 
When the xml is ready you can run it this way:
{{Keyboard|content=<syntaxhighlight lang="bash">C:\>psarc.exe --xml=C:\DTD_Layout.xml</syntaxhighlight>}}
 
The options '''--verbose''', '''--debug''', and '''--quiet''' cant be used inside the xml, so if needed are specifyed in the command line, this way:
{{Keyboard|content=<syntaxhighlight lang="bash">C:\>psarc.exe --debug --xml=C:\DTD_Layout.xml</syntaxhighlight>}}

===create===
* Create an archive.
 
====create by directory====
Creates a psarc using the contents of a specified folder and all subfolders. Is only available when using an .xml because command line doesn't allow to specify a source folder
 
Is the most rude method to create a psarc because all folders and files will be archived alphabetically based in his names (there is no control of the ID's that will be assigned to each file in the '''manifest'''). Cant be used to rebuild psarcs
 
Note in the next example the file dummy.txt (located in the root of the folder in windows, so considered first) has been archived after BMPfolder1

====create by filelist====
This method allows to order the files inside the archive in a specific position (so is posible to know the ID that will have every files before creating the psarc)
 
When rebuilding a psarc from a game is needed to preserve the original ID's of ALL the files inside the archive (is posible to replace files but never remove). By replacing files (e.g: by dummyes) all the others preserves his positions
 
The filelist is a plain .txt file where every file is defined by a single line, composed by his path, filename, and file extension, 1 line per file. Is posible to generate this kind of filelists automatically by using the output of the '''--list''' command and some regular expressions to replace characters
 
The examples used in wiki uses full PC paths to be more flexible (no need to place psarc.exe next to the source folder, actually you can place psarc.exe in c:\ the source folder in d:\ and create the psarc in x:\). When using full paths is mandatory to use the '''--strip''' option with an explicit path or a regular expression (regex) to remove part of the PC path (e.g: if you strip '''C:\psarctests\source files\test''' from '''C:\psarctests\source files\test\BMPfolder1\Image1.bmp''' the resulting path of the file inside the archive will be '''BMPfolder1/Image1.bmp''')
 
The '''--strip''' option removes part of the paths from the filelist, can be used several times with different stripped paths, this is usefull when the psarc archive is generated from a filelist that contains paths from different folders and/or devices in the PC (e.g: is posible to create a filelist including a file from '''F:\textures\packed\texture1.jpg''' and another file from '''G:\models\packed\model1.xxx''' and strip the paths: '''F:\textures\''' and '''G:\models\''', this way both files will be stored inside the psarc archive together under path: '''packed/texture1.jpg''' and '''packed/model1.xxx''')
 
First is needed to prepare a '''filelist.txt''' like this example, located in '''C:\psarctests\source files\filelist.txt''', contains the PC paths of the files that are in the folder '''C:\psarctests\source files\test''' and will be included inside the psarc archive:
C:\psarctests\source files\test\dummy.txt
C:\psarctests\source files\test\BMPfolder1\Image1.bmp
C:\psarctests\source files\test\JPGfolder1\JPGfolder2\Image2.jpg
C:\psarctests\source files\test\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png
 
The psarc archive is created by using the filelist as the '''--inputfile''' and uses an explicit path to '''--strip''' from every file inside the filelist, this way:
{{Keyboard|content=<syntaxhighlight lang="bash">C:\>psarc.exe create --strip="C:\psarctests\source files\test" --output=C:\psarctests\by_filelist.psarc --inputfile="C:\psarctests\source files\filelist.txt"</syntaxhighlight>}}
 
Or you can prepare an .xml that contains the path to the filelist.txt
{{Boxcode|title=Create_by_filelist.xml|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\by_filelist.psarc" absolute="false" ignorecase="false">
<compression type="zlib" enabled="true" />
<strip regex="C:\psarctests\source files\test" />
<filelist path="C:\psarctests\source files\filelist.txt" />
</create>
</psarc>
</syntaxhighlight>}}
 
Then run the contents of the .xml this way:
{{Keyboard|content=<syntaxhighlight lang="bash">C:\>psarc.exe --xml="c:\psarctests\CREATE by_filelist.xml"</syntaxhighlight>}}
 
The output of the tool is the same in both cases (except the InputFile not present when using an xml)

====create by file====
This method is the real deal, only available by using an xml, superceedes all the other creation methods and is the only method where is posible to use per-file attributes
 
The xml includes a list of files where every path of every file in the PC is specifyed (paths are the same than the filelist.txt explained before) but every file line allows for attributes
 
Note in the next example the compression attribute is enabled and affects all files, except Image3.png that has been archived without compression (appears as 100% in the list command output)
 
The other per-file attribute avoids the tool to output an error in the case the file dummy.txt is missing in the source folder

Batch. This is an useless example to show how the .psarcs are created sequentially and how to create several .psarc's with only one .xml, it uses all default values for compressions, formats, flags etc...
 
In step 1 it creates an egg.psarc containing a dummy.txt. In step 2 it creates a chiken.psarc containing the egg.psarc made in step 1. In step 3 it creates an egg.psarc containing the chicken.psarc made in step 2 (egg.psarc created in step 3 overwrites egg.psarc made in step 1)

===extract===
* Extract contents of an existing archive.
*There are 3 optional available attributes for extract:
**'''--overwrite''' (if the files existed in the extraction folder they will be overwritten without advise)
**'''--strip-all''' (extracts all files in the root of the target folder, incase of several extracted files with the same name the program will return an error, this can be solved by using the command --overwrite)
**'''--skip-missing-files''' (seems pointless, mostly to extract files from malformed .psarcs or .psarcs that doesnt passes the "verify" command ?)
 
The required options are '''--input''' (the source .psarc) and '''--to''' (the target folder where contents will be extracted)
 
====extract all====
The example command extracts all files from the .psarc to a directory with full directory tree names, no skipped missing files, no overwrite
 
When using this options the command line output is the same, there is no mention of wich files are stripped, overwritten, or missing in the extraction process

</syntaxhighlight>}}
 
====extract by file====
This extraction method is only available when using an xml because command line doesnt allows to specify files inside the archive
 
{{Boxcode|title=Extract_by_file.xml|code=<syntaxhighlight lang="xml">
<psarc>
<extract archive="C:\psarctests\source files\test.psarc" to="C:\psarctests\by_file">
<file archivepath="BMPfolder1/Image1.bmp" />
</extract>
</psarc>
</syntaxhighlight>}}
{{Keyboard|content=<syntaxhighlight lang="bash">
C:\>psarc.exe --xml="c:\psarctests\EXTRACT by_file.xml"
Extracting: BMPfolder1/Image1.bmp (6220854 bytes)
</syntaxhighlight>}}
 
When extracting single files is also posible to use the same attributes availables in command line, and attributes per-file, but they uses different names inside the xml (see the DTD example)
{{Boxcode|title=Extract_by_file.xml|code=<syntaxhighlight lang="xml">
<psarc>
<extract archive="C:\psarctests\source files\test.psarc" to="C:\psarctests\by_file" stripall="true" skipmissingfiles="false" overwrite="true">
<file archivepath="dummy.txt" skipifmissing="true" />
<file archivepath="PNGfolder1/PNGfolder2/PNGfolder3/Image3.png" />
</extract>
</psarc>
</syntaxhighlight>}}
 
*Notes about the xml examples above:
**The element "extract" uses the attribute '''archive''' but could be replaced by '''input''', in this case are exactly the same and both will work, actually '''--input''' is the same option used in comand line but the examples in wiki uses the name '''archive''' because is more intuitive (is also used as an attribute for "create" and in both cases is refered to the compressed archive.psarc). Both (archive and input) appears in the DTD as optional (#IMPLIED) but only one of them can be used in the xml
**The element "file" uses the attribute '''archivepath''' but could be replaced by '''path''', in this case are exactly the same and both will work, but the examples in wiki uses the name '''archivepath''' because is more intuitive (is refered to the path of a file inside archive.psarc). Both (archivepath and path) appears in the DTD as optional (#IMPLIED) but only one of them can be used in the xml
 
===Other options===
 
====Regular expression support (regex)====
-sREGEX, --strip=REGEX                  Perl-compatible regex specifying a prefix to strip from the pathnames stored in the archive. This may be specified more than once. (default = current dir)
 
Psarc uses regular expressions compatibles with PERL 5, specifically the ones used by the PCRE library http://www.pcre.org/ As can be seen in the PS3 firmware third party software licenses in XMB/Settings/System Settings/About PlayStation®3 (PS3™)
 
====Compression levels====
--level=N                              Compression quality. 1 is fastest, 9 is best. (default = 9)
 
*Notes
**(default = 9)
**when --level is not defined at creation time, the info about compression level in the creation process window appears with a value of 9, even when using --nocompress
 
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\by_file.psarc">
<compression type="zlib" level="9" />
...
</syntaxhighlight>}}
 
====Create mself====
-m, --mself                            Create a PSARC-MSELF hybrid file for PS3, which can contain encrypted special files like SDATA, SPRX, and SPU SELF.
 
For rebuilding purposes is needed to verify if some of this files are present in the original filelist, by searching for this file extensions (.sdata .sprx and .self), though file extensions could not be accurate because game developers can use custom names for file extensions
 
*As far i remember this option doesnt stores any data in the psarc header so it seems the only way to identify his presence is by looking at the files itself--[[User:Sandungas|Sandungas]] ([[User talk:Sandungas|talk]]) 18:34, 20 March 2017 (UTC)

=Rebuilding PSARC files=
When rebuilding a psarc is needed to preserve the original positions of all the files inside the archive (because every file in the original psarc has assigned an '''ID''' number, and after rebuilding this numbers must match with the original positions). for this same reason when rebuilding is not a good idea to remove files (because the other files that comes after will be displaced). When the purpose of the rebuild is to  reduce the size (by removing languages, etc...) the method consists in replacing them by dummies (0kb files), this dummies preserves the positions of all the files
 
This need to preserve the original positions of all the files inside the archive in the practise means there are only 2 methods to rebuild a psarc: "by filelist" or "by file". For both is needed to create a list of files
 
{{Boxframe3|content='''Rebuilding PSARC files, step-by-step summary'''

* Step 2 - Identify if per-file compression was used <!-- and dupes --->
* Step 3 - Rebuild

** Step 3a - If per-file compression was used, rebuild with the method "by file"
* Step 4 - Verify
}}
 
'''Step 1'''
 
Is needed to look at the psarc header to identify some settings
'''Offset(h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F'''
00000000  50 53 41 52 00 01 00 04 <span style="background:#ffff66;">7A 6C 69 62</span> 00 01 23 BA  PSAR....<span style="background:#ffff66;">zlib</span>..#º
00000010  <span style="background:#dd00dd;">00 00 00 1E</span> 00 00 09 16 <span style="background:#dddddd;">00 01 00 00</span> <span style="background:#d0000d;">00 00 00 03</span>  ................
 
Most important ones are the '''<span style="background:#ffff66;">compression method</span>''' (zlib/lzma) and the '''<span style="background:#d0000d;">archive flags</span>''' (relative/absolute, and ignorecase), this settings will be used when rebuilding from command line or from xml this way:
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\by_file.psarc" absolute="true" ignorecase="true">
<compression type="zlib" />
...
</syntaxhighlight>}}
 
The other values in the header that needs to be verifyed are the '''<span style="background:#dd00dd;">TOC entry size</span>''' and the '''<span style="background:#dddddd;">Block size</span>''', is needed to know if the original psarc we are trying to rebuild uses the default values (all i found used defaults), otherway is posible to use non-default values this way: <!-- not sure if is posible to change the "TOC entry size" -->
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\by_file.psarc" absolute="true" ignorecase="true" blocksize="65536">
<compression type="zlib" />
...
</syntaxhighlight>}}
 
'''Step2'''
 
Now is needed to know if the psarc uses per-file compression (if some of the files inside the archive are compressed, and others are not compressed)
 
This is important to know wich rebuild method will be used in the next step, is needed to make a --list command with psarc tool and store the output of the command as a .txt
 
Open the .txt in a text editor (like notepad++) and search for the string '''100%''' (the files that appears with a 100% has been archived but are not compressed). Is needed to do it this way semi automatized because is usual to find psarc with thousand of files inside
 
*Check how many files are not compressed, his sizes, and file extensions
**If there are no files with 100% or if there are only a few and his sizes are minimal this is normal, it means the archive doesnt uses per-file compression
**If there some files with the 100%, normal sizes (not minimal), using the same file extension, and can be identifyed (like audio or video formats) then you have a psarc with per-file compression
**If all the files appears as 100% it means the psarc has been created with the compression attibute set as "false" this way:
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\by_file.psarc" absolute="true" ignorecase="true" blocksize="65536">
<compression type="zlib" enabled="false" />
...
</syntaxhighlight>}}
 
'''Step3'''
 
If the psarc doesnt uses per-file compression then is posible to rebuild it with the '''create by filelist''' method from command line by using an external filelist.txt
 
If the psarc uses per-file compression then the only way to rebuild it is with the '''create by file''' method by using an xml (the xml includes a list of files like the filelist.txt)

*Special rebuild notes:
**Mass effect 3 MAIN.PSARC contains a group of generic files compressed with level 9, and another group of .TXT, .BIN, and .BIK videos not compressed at all. In the creation options suggested above in the table the compression level is not defined and this means all them will use the default compression level 9 (so the .BIK files will have a ridiculous 1% or 2% of compression ratio because is the max they will admit). This is not how the original file was created (but works), the correct way to rebuild it is by defining specific compression levels "per file" in a predefined .xml
**Killzone 3 data_ps3.psarc (BCES01007 version) contains 8324 files (included 5.3GB of audio files for 21 languages with a compression of around 50%)... 2883 of all the files uses the same path/filenames repeated up to 3 times (because was created using 3 or more different working directories). This duplication of paths/filenames inside the .psarc in the practise means when doing a standard extraction 2833 files will be missing, overwrited, or they will give an error at extraction time, the correct way to mess with it is by doing several partiall extractions to different directories, and rebuild it by using a preconfigured .xml where the different paths for each file are specifyed, when rebuilding is also needed to use the --strip option several times to remove part of the paths from all the different working directories, this way the paths/filenames will be duplicated inside the .psarc archive (but are different files located at different positions and with a different ID number assigned).
**Ape Escape target.psarc includes "dupes" (or duplicated files) in the TOC (table of contents) of the psarc archive. This method used at creation time basically works by making several entries of the TOC to point to the same file, this way a single file inside the psarc is indexed several times in the TOC and can be accessed from several different paths/filenames. The only way to identify this dupes before extraction is by reading the TOC of the psarc for all the files and compare wich position are pointing to. As an example the original size of target.psarc is 328mb... after a "standard" extraction is 2.52GB (this extraction doesnt identify the dupes so are extracted several times under different paths/filenames)... if you try to rebuild it again his final size will be much bigger than the original target.psarc

*The file paths inside filelist.txt or inside an xml admits 2 formats:
**'''full PC paths''' (where the full PC file path included the device letter is used by psarc.exe to locate the file in any device and/or any folder). This method is the most flexible but needs an '''strip''' command to remove part of the PC path when creating the psarc archive
**'''relative to work directory paths''' (where work directory is the path to psarc.exe and the files needs to be placed in a subfolder under it). This method needs to copy psarc.exe to the parent folder of the files
 
The file list we need to generate contains the access paths stored in the '''manifest''', the easy way to have have a copy of the manifest is by using the '''list''' command of psarc tool
 
The output of the '''list''' command has some characters that are needed ro remove or replace, the purpose of automatizing this process by using regular expressions is because usually psarc files contains thousand of files, the examples used here are commands for fnr.exe (find and replace tool) and contains regular expressions (to search) and a character strings (to replace)
 
===Generating a filelist.txt by using regular expressions===
{{Boxframe3|content='''Generating a filelist.txt, step-by-step summary'''
* Step 1 - Save list command output as a .txt
* Step 2 - Remove first line
* Step 3 - Remove parentheses
* Step 4 - Remove last line
* Step 5 - Replace slashes (optional, recommended)
* Step 6 - Add local paths (optional, recommended)
** Step 6a - Absolute flag blind fix (optional, recommended)
}}
 
*'''Step 1 - Save list command output as a .txt'''
Generate a .txt file containing the output of the '''list''' comand
{{Boxframe1|content=
{{Keyboard|content=<syntaxhighlight lang="bash">C:\>psarc.exe list "C:\psarctests\source files\test.psarc" > "C:\psarctests\filelist.txt"</syntaxhighlight>}}
The file generated by the list command will have this content (note there is en empty line at the end):
Listing C:\psarctests\source files\test.psarc
dummy.txt (0/0 100%)
BMPfolder1/Image1.bmp (8018/6220854 0%)
JPGfolder1/JPGfolder2/Image2.jpg (209/12524 1%)
PNGfolder1/PNGfolder2/PNGfolder3/Image3.png (6142/6142 100%)
<br>}}
 
*'''Step 2 - Remove first line'''
{{Boxframe1|content=
find (and replace by nothing):
Listing.*\n
The resulting file:
dummy.txt (0/0 100%)
BMPfolder1/Image1.bmp (8018/6220854 0%)
JPGfolder1/JPGfolder2/Image2.jpg (209/12524 1%)
PNGfolder1/PNGfolder2/PNGfolder3/Image3.png (6142/6142 100%)
<br>}}
 
*'''Step 3 - Remove parentheses'''
{{Boxframe1|content=
find (and replace by nothing):
[^\b]\(.*\)
The resulting file:
dummy.txt
BMPfolder1/Image1.bmp
JPGfolder1/JPGfolder2/Image2.jpg
PNGfolder1/PNGfolder2/PNGfolder3/Image3.png
<br>}}
 
*'''Step 4 - Remove last line'''
{{Boxframe1|content=
find (and replace by nothing):
\r\n$
The resulting file:
dummy.txt
BMPfolder1/Image1.bmp
JPGfolder1/JPGfolder2/Image2.jpg
PNGfolder1/PNGfolder2/PNGfolder3/Image3.png
<br>}}
*'''Step 5 - Replace slashes (optional, recommended)'''
This step is optional, both slashes are valid, but is good to do it to standarize all paths formats, otherway is a mess
{{Boxframe1|content=
find:
/
replace by:
\\
The resulting file:
dummy.txt
BMPfolder1\Image1.bmp
JPGfolder1\JPGfolder2\Image2.jpg
PNGfolder1\PNGfolder2\PNGfolder3\Image3.png
<br>}}
 
*'''Step 6 - Add local paths (optional, recommended)'''
Now is needed to add the local paths (where the psarc contents are decompressed), e.g: '''C:\psarctests\source files\test\''', remember this is exactly the part of the path that is needed to '''strip''' later (because we dont want to include our local path '''C:\psarctests\source files\test\''' inside the manifest)
 
This is a perfect filelist.txt that can be used for the rebuild method '''by filelist''' from command line (usefull when the psarc doesnt uses per-file compression), remember is needed to use the '''strip''' option
{{Boxframe1|content=
find:
^
replace by:
C:\\psarctests\\source files\\test\\
The resulting file:
C:\psarctests\source files\test\dummy.txt
C:\psarctests\source files\test\BMPfolder1\Image1.bmp
C:\psarctests\source files\test\JPGfolder1\JPGfolder2\Image2.jpg
C:\psarctests\source files\test\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png
<br>}}
 
*'''Step 6a - Absolute flag blind fix (optional, recommended)'''
The purpose of this step is to fix a posible problem that could appear in step 6, the psarc used as an example in step 1 to generate the initial list of files was created without '''archive flags''' (in other words, his access paths in the manifest was '''relative''' paths)
 
The other posible paths format used by the manifest is when the psarc was created with '''absolute''' archive flag, in this case all the lines of the file list in step 5 starts with an slash \ (e.g: the first file in the list that is supposed to be archived in the root of the psarc should be listed as '''\dummy.txt''' instead of '''dummy.txt'''
 
In step 6 is added a local path that ends with an slash too... so the result is '''C:\psarctests\source files\test\\dummy.txt''' (note the double slash), this is wrong and this step fixes it blindlly (because doesnt matters if the problem exists or not, the final result will be the same)

===Generating a XML by using regular expressions===
{{Boxframe3|content='''Generating a xml, step-by-step summary'''
* Step 1 - Save list command output as a list.txt
* Step 2 - Replace slashes
* Step 3 - Replace first line start (preserves original .psarc path)
* Step 4 - Replace first line end (for relative flag)
* Step 5 - Replace first line end (for absolute flag)
* Step 6 - Replace parentheses (per-file compression autodetection)
* Step 7 - Replace other parentheses
* Step 8 - Replace last line
* Step 9 - Absolute flag blind fix
}}
 
*'''Step 1 - Save list command output as a list.txt'''
Generate a list.txt file containing the output of the '''list''' command
{{Boxframe1|content=
{{Keyboard|content=<syntaxhighlight lang="bash">C:\>psarc.exe list "C:\psarctests\source files\test.psarc" > "C:\psarctests\list.txt"</syntaxhighlight>}}
The file generated by the list command will have this content:
{{Boxcode|code=<syntaxhighlight lang="xml">
Listing C:\psarctests\source files\test.psarc
/dummy.txt (0/0 100%)
/BMPfolder1/Image1.bmp (8018/6220854 0%)
/JPGfolder1/JPGfolder2/Image2.jpg (209/12524 1%)
/PNGfolder1/PNGfolder2/PNGfolder3/Image3.png (6142/6142 100%)
 
</syntaxhighlight>}}
*Notes of the example:
**The original path of the .psarc is '''C:\psarctests\source files\test.psarc''' (it will be used as the path where the rebuild .psarc will be created)
**Paths starts with an slash  '''/''' (so the .psarc was created with absolute flag)
**'''dummy.txt''' and '''Image3.png''' was archived without compression (appears with 100%)
**There is an empty line at the end (not visible in wiki because yeah... is empty)
}}
 
*'''Step 2 - Replace slashes'''
This step is to standarize paths formats
{{Boxframe1|content=
find:
/
replace by:
\\
The resulting file:
{{Boxcode|code=<syntaxhighlight lang="xml">
Listing C:\psarctests\source files\test.psarc
\dummy.txt (0\0 100%)
\BMPfolder1\Image1.bmp (8018\6220854 0%)
\JPGfolder1\JPGfolder2\Image2.jpg (209\12524 1%)
\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png (6142\6142 100%)
</syntaxhighlight>}}
}}
 
*'''Step 3 - Replace first line start (preserves original .psarc path)'''
This step keeps the original local path of the .psarc file that appears in the output of the list command (is the path where the .psarc will be created)
{{Boxframe1|content=
find:
Listing.
replace by:
<psarc>\r\n\t<create archive="
The resulting file:
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\source files\test.psarc
\dummy.txt (0\0 100%)
\BMPfolder1\Image1.bmp (8018\6220854 0%)
\JPGfolder1\JPGfolder2\Image2.jpg (209\12524 1%)
\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png (6142\6142 100%)
</syntaxhighlight>}}
}}
 
*'''Step 4 - Replace first line end (for relative flag)'''
Relative paths is the default value, this step completes the replacement of the first line by using the default '''absolute="false"''' attribute
{{Boxframe1|content=
find:
\.psarc\r\n
replace by:
\.psarc" absolute="false" ignorecase="false">\r\n\t\t<compression type="zlib" />\r\n\t\t<strip regex="C:\\source\\folder\\" />\r\n\r\n\t\t<file path="C:\\source\\folder\\
The resulting file:
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\source files\test.psarc" absolute="false" ignorecase="false">
<compression type="zlib" />
<strip regex="C:\source\folder\" />
 
<file path="C:\source\folder\\dummy.txt (0\0 100%)
\BMPfolder1\Image1.bmp (8018\6220854 0%)
\JPGfolder1\JPGfolder2\Image2.jpg (209\12524 1%)
\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png (6142\6142 100%)
</syntaxhighlight>}}
}}
 
*'''Step 5 - Replace first line end (for absolute flag)'''
This step finds the same pattern replaced in step before followed by an slash, if found is replaced by the same pattern but with '''absolute="true"''' attribute
{{Boxframe1|content=
find:
\.psarc" absolute="false" ignorecase="false">\r\n\t\t<compression type="zlib" />\r\n\t\t<strip regex="C:\\source\\folder\\" />\r\n\r\n\t\t<file path="C:\\source\\folder\\\\
replace by:
\.psarc" absolute="true" ignorecase="false">\r\n\t\t<compression type="zlib" />\r\n\t\t<strip regex="C:\\source\\folder\\" />\r\n\r\n\t\t<file path="C:\\source\\folder\\\\
The resulting file:
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\source files\test.psarc" absolute="true" ignorecase="false">
<compression type="zlib" />
<strip regex="C:\source\folder\" />
 
<file path="C:\source\folder\\dummy.txt (0\0 100%)
\BMPfolder1\Image1.bmp (8018\6220854 0%)
\JPGfolder1\JPGfolder2\Image2.jpg (209\12524 1%)
\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png (6142\6142 100%)
</syntaxhighlight>}}
}}
 
*'''Step 6 - Replace parentheses (per-file compression autodetection)'''
This step replaces only the parentheses for the lines of the files that was archived without compression and adds the attribute '''compressed="false"'''
{{Boxframe1|content=
find:
[^\b]\(.*100.\)\r\n
replace by:
" compressed="false" />\r\n\t\t<file path="C:\\source\\folder\\
The resulting file:
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\source files\test.psarc" absolute="true" ignorecase="false">
<compression type="zlib" />
<strip regex="C:\source\folder\" />
 
<file path="C:\source\folder\\dummy.txt" compressed="false" />
<file path="C:\source\folder\\BMPfolder1\Image1.bmp (8018\6220854 0%)
\JPGfolder1\JPGfolder2\Image2.jpg (209\12524 1%)
\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png" compressed="false" />
<file path="C:\source\folder\
</syntaxhighlight>}}
}}
 
*'''Step 7 - Replace other parentheses'''
This step replaces all the other parentheses for the lines of the files that willl be compressed
{{Boxframe1|content=
find:
[^\b]\(.*\n
replace by:
" />\r\n\t\t<file path="C:\\source\\folder\\
The resulting file:
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\source files\test.psarc" absolute="true" ignorecase="false">
<compression type="zlib" />
<strip regex="C:\source\folder\" />
 
<file path="C:\source\folder\\dummy.txt" compressed="false" />
<file path="C:\source\folder\\BMPfolder1\Image1.bmp" />
<file path="C:\source\folder\\JPGfolder1\JPGfolder2\Image2.jpg" />
<file path="C:\source\folder\\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png" compressed="false" />
<file path="C:\source\folder\
</syntaxhighlight>}}
}}
 
*'''Step 8 - Replace last line'''
This step replaces a useless line at the end and completes the xml structure
{{Boxframe1|content=
find:
\t\t<file path="C:\\source\\folder\\$
replace by:
\t</create>\r\n</psarc>
The resulting file:
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\source files\test.psarc" absolute="true" ignorecase="false">
<compression type="zlib" />
<strip regex="C:\source\folder\" />
 
<file path="C:\source\folder\\dummy.txt" compressed="false" />
<file path="C:\source\folder\\BMPfolder1\Image1.bmp" />
<file path="C:\source\folder\\JPGfolder1\JPGfolder2\Image2.jpg" />
<file path="C:\source\folder\\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png" compressed="false" />
</create>
</psarc>
</syntaxhighlight>}}
}}
 
*'''Step 9 - Absolute flag blind fix'''
The purpose of this step is to fix a posible problem that only happens when the .psarc was created with absolute flag (when the paths created from the list command starts with an slash, like in the examples)
 
The fix is made blindlly because it will remove an slash only if two consecutive slashes are found (if there are no double slashes it will do nothing)
{{Boxframe1|content=
find:
\\\\
replace by:
\\
The resulting file:
{{Boxcode|code=<syntaxhighlight lang="xml">
<psarc>
<create archive="C:\psarctests\source files\test.psarc" absolute="true" ignorecase="false">
<compression type="zlib" />
<strip regex="C:\source\folder\" />
 
<file path="C:\source\folder\dummy.txt" compressed="false" />
<file path="C:\source\folder\BMPfolder1\Image1.bmp" />
<file path="C:\source\folder\JPGfolder1\JPGfolder2\Image2.jpg" />
<file path="C:\source\folder\PNGfolder1\PNGfolder2\PNGfolder3\Image3.png" compressed="false" />
</create>
</psarc>
</syntaxhighlight>}}
