       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
  • Create list of files from data.psarc : PSARC -l data.psarc
  • Extract file with File ID 5 : PSARC -e 5 5 data.psarc
  • Extract files with File ID 7 through 12 : PSARC -e 7 12 data.psarc

The flag -l creates a .txt file with a list of all the contents of the archive, the info included is: File ID, File original size, and File path inside psarc archive

Example of a .txt file created with the -l flag:

ID       Size         Name
