The compression algorithms, the PS3 system, and the .psarc format, allows for 9 compression levels but in the practise 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) doesnt admits much compression because are already compressed originally (as example, max compression ratio for .BIK video and .MP3 audio doesnt reachs 1% or 2%). For this reason is better to dont 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) doesnt 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 applyed 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 | |||

====extract | ====xml extract==== | ||
To use an .xml is needed to prepare it before using psarc.exe, using an xml is the most flexible way to use psarc.exe because allows to place the source (files to create, or psarc to extract), target (files to create, or psarc to extract), and psarc.exe in any path of the PC, it allows the usage of a filelist.txt (that defines all files inside the archive), create psarcs based in a directory, or specify all the files inside the xml, also to specify the compression level for every file (needed for video or audio files that doesnt admits compression), etc... | |||
Is also the most complicated method because is needed to specify full PC paths inside the xml, and when creating is needed to specify regular expressions to strip part of the PC path | |||
{{Keyboard|content= | When the xml is ready you can run it this way: | ||

Both (archivepath and path) appears in the DTD as optional (#IMPLIED) but only one of them can be used in the xml | ||
**To identify the paths inside the psarc archive use '''--list''' option in command line. By default the paths inside the psarc are relative (path names starts with the name of the folder) but in some cases the paths starts with a slash"/" (when the psarc has been created with '''absolute''' flag), in this case the slash needs to be specifyed as part of the path here (e.g: '''archivepath="Folder1/Image1.bmp"''' is a relative path, and '''archivepath="/Folder1/Image1.bmp"''' is an absolute path) | |||
=== | ====create==== | ||
* Create an archive. | |||
Ther are 3 different ways to create a psarc archive (by '''directory''', by '''filelist''', or by '''file'''). '''By directory''' creates the psarc using the contents of a specifyed folder and all subfolders, all them ordered alphabetically (windows style), this method cant be used to rebuild psarcs where every file needs to be assigned with an specific ID (and im not sure if is available in command line). '''By file''' means every path of every file in the PC is needed to be specifyed and this is not posible in command line when the archive has lot of files (for a single file is fine, but when are thousand of files is a no way). For this reason the only method explained here is '''by filelist''' | |||
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, in any order (not needed to be ordered alphabetically). Is posible to generate this kind of filelists automatically by using the output of the '''--list''' command and some regular expressions to replace characters (this is long explain and doesnt fits here by now) | |||
As explained before, the examples used here 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 '''psarctests\custom_folders_extracted\''' from '''c:\psarctests\custom_folders_extracted\Folder1\Image1.bmp''' the resulting path of the file inside the archive will be '''Folder1\Image1.bmp''') | |||
In the next example the filelist is in '''c:\psarctests\custom_folders_filelist.txt''' and contains the PC paths of the files that will be included inside the psarc archive: | |||
C:\psarctests\custom_folders_extracted\Folder1\Image1.bmp | |||
C:\psarctests\custom_folders_extracted\Folder2\Folder21\Image21.png | |||
C:\psarctests\custom_folders_extracted\Folder3\Folder31\Folder311\Image311.jpg | |||

*Notes: | |||
**The program replaces the windows slash "\" by "/" when archiving the files (note the difference in the creation process between '''Archiving C:/...''' and '''Compressing C:\...'''). When making a '''--list''' command over the created psarc the slashes will appear as "/" because this is how they was archived in the '''Manifest''' (manifest is the first file inside the psarc filetable, doesnt appears as a file when using the '''--list''' command and doesnt have an assigned '''ID''') | |||
**'''--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''') | |||

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 sze (by removing languages, etc...) the method consists in replacing them by dummies (0kb files), this dummies preserves the positions of all the files | |||

To be sure all the files are in the correct positions can be used as a base file (to edit later) the output of the '''list''' command as explained before | |||
This edition of the file generated by the '''list''' command can be automated completly (not needed to edit a single character by hand). Is posible to generate a '''filelist.txt''' or an '''automated.xml''' by replacing/erasing/adding characters with other programs that identifies and replaces characters by using regular expressions, the examples used here are commands for fnr.exe (find and replace tool) and contains regular expressions (to search) and a character string (to replace) | |||

*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 | |||
