The compression algorithms, the PS3 system, and the. psarc contents by reading the archive flags that are needed to process the access paths in the manifest 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. There are 3 different methods to generate this paths that defines how the.
