Downloaded Backup not showing up in MultiMan

I downloaded FIFA 13 from torrent download and extracted the compressed files into a new folder. In the folder (BLES01676-[FIFA 13]) with the extracted files, I have:

• BLES01676-[FIFA 13]
  - - PS3_GAME
  - - PS3_UPDATE
  - - PS3_DISC.SFB

I have copied the parent folder (BLES01676-[FIFA 13]) into a FAT partition of an external hard drive I usually use to copy games to and from my 3.55 jailbroken PS3 with no issue, however FIFA 13 isn't listed in MultiMan. I've also tried to put the folder into "GAMES" and also "GAMEZ" (which isn't required with other games, I think) with no luck.
Lest I mention, I used the Eboot patch (Duplex-fifa13ebootpatch PROPER FIX.zip) to overwrite the corresponding folders.

Thanks for any help.
