PS3 Harddrive Layout

The PS3 harddrive (dev_hdd0) layout looks as follows:

  • data
    • bootflag.dat
  • drm
  • game
    • GameFolderName1
      • USRDIR
        • EBOOT.BIN
      • ICON0.PNG
      • PARAM.SFO
      • PIC1.PNG
      • PS3LOGO.DAT
    • GameFolderName2...
  • home
  • mms
  • vsh
  • widget

Installed games would have its own folder under the game folder, and EBOOT.BIN from each game's USRDIR would be run to boot the game. Games downloaded from the PlayStation Network are actually one large packaged .pkg file. When you install the .pkg file is expanded and dumped into the /game directory of the harddrive in its own folder. The contents hierarchy of the .pkg file would look like the above (residing in its own /game folder of course). There is a limit of 4GB per file on the harddrive (same as on the Blu-ray disc). Game demos (because they are packaged in a .pkg file) cannot exceed 4GB in size. The /data/bootflag.dat most likely tells the PS3 to boot into XMB or the OtherOS (linux).
