September 26, 2010 // 8:37 pm - Today PSGroove has shared details courtesy of inf1 on how to run PS3 games which contain 4+GB files from an external PlayStation 3 FAT32 HDD.

Those interested can check out the guide below, and be sure to share your results in our PS3 JailBreak Game Compatibility List.

To quote: Due to FAT32 limitations users needed to run these games from internal hard drive only. However, it seems that isn't the only option anymore. Many games utilize a file format known as PSARC (*.psarc).

These files ending in .psarc are archive files similar to zip or rar files on PC. By extracting these large archive files and using the smaller files that are inside, users can get stay under the 4GB limit.

This method has been tested on Uncharted II, and will only work on games utilizing the psarc file format.

1) Download PSARC.zip PlayStation Archive Utility (or the PARC GUI v0.1 or the PARC GUI v0.2 update by TeamKidneyBean if you prefer).
2) Extract zlib.net.dll and PSARC.exe to any folder.
3) Find any files more than 4Gb for example /PS3_GAME/USRDIR/build/main/pak22.psarc (5,596,444,529 bytes)
4) Copy pak22.psarc into zlib.net.dll and PSARC.exe directory.
5) Extract pak22.psarc (just drag-n-drop pak22.psarc to PSARC.exe)
6) Now copy pak22 folder with extracted files to gamefolder /PS3_GAME/USRDIR/build/main
7) Now you can delete pak22.psarc.
8) Copy PS3_GAME folder with game to your external fat32 usb hdd GAMEZ/Uncharted2/
9) Use Backup Manager to load game, should work fine.

I've created a Gui to do this automatically, and recompiled to use .Net 2 rather than .Net 4

It's still untested as im awaiting my JB device, but in theory should work!

Will this be useful in Final Fantasy 13 ? I guess not because the +4GB file in ff13 is a video.

Somebody with this game can confirm ?

Thanks man, what you said was true.

This is just bug in FTP software showing the incorrect file sizes for larger files

If you remove the drive and put it into an external hdd casing, connect it to the USB ports then theoretically it should be able to read the drive. But it doesn't for some reason. Now if that reason can be targetted and resolved, we would not have to worry about large files on the external drives.


Sadly - this is not possible - PS3 will not read internal format of hard drive as external.

500GB , but its like WBFS really when we had to format a wii drive in mac format, I cannot remember what type of format (smoke too much) but would this work instead of ntfs?

Just a suggestion...

Well it works, I used this to play tekken 6 and uncharted 2, though tekken 6 got some STUPIDLY long loadtimes, uncharted 2 worked perfectly.

Not sure but it seems like a coding problem in tekken 6, it just seemed like it was just sitting there doing nothing most of the time (my thought was maybe it waits for some kind of timeout, or maybe it just searches through the entire drive to find the file)

It wasn't particularly playable at least imo when it comes to tekken6.. No doubt it's a step forward at least as it will work on some games.
