These files are stored on the PS3 HDD (hdd0/home/00000001/savedata/your game folder), and can be copied over to a media through USB or similar. There are two types, those which are encrypted+signed, and those which aren't neither. This allows modifications/cheats for some games, yes. When copied, they are put inside these folder called "PS3\SAVEDATA\", followed by their Title ID. I'd like to call the encrypted+signed saves as protected saves.
These files are stored on the path: hdd0/home/'''<userid>'''/savedata/'''SAVEDATA_DIRECTORY''', where:

*'''<userid>''' is the number the system assigned to this user when his account was created (is a counter). Stored in [[XRegistry.sys]], e.g: '''00000001'''.
All games define their own sub folder(s) based on the following pattern

PS3 Saved Games

These files are stored on the path: hdd0/home/<userid>/savedata/SAVEDATA_DIRECTORY, where:

  • <userid> is the number the system assigned to this user when his account was created (is a counter). Stored in XRegistry.sys, e.g: 00000001.
  • SAVEDATA_DIRECTORY is the name of the folder, composed by TITLE_ID + some variable characters, e.g: BLES00001-savedata. Stored inside the PARAM.SFO of this GameSave

There are two types of possible protections:

  • One possible encryption in the files generated by the game that is not mandatory and depends of the developers of the game.
  • And other protection based on signatures stored in PARAM.PFD generated and managed by the system. This file supervises signatures of other files of the folder, the list of files supervised is not fixed and again... it depends of the developers of the game, but usually PARAM.SFO is inside this list

This allows modifications/cheats for some games wich files are not encrypted, and not supervised by PARAM.PFD

Some games are "copy-protected", but the others can be copyed to a externall USB device in the path usb0\PS3\SAVEDATA\SAVEDATA_DIRECTORY
