I have transfered a Movie bigger than 4gb on the PS3 then why doesn't the FAT32 file size limitation come in

I believe that limitation is a windows thing,  I dont believe the PS3 has those limtations

NAH the limitations are FAT32 file structure based and still on PS3 its different

Yes but those limitations are based off of Windows applications and such.  The PS3 doesnt hve any file limitations Otherwsie I couldnt have files on my PS3 that are over 6-7GB

thats what i'm confused about

i was just saying as you were not sure about it

and i have been discussing this at other places and they say that its not windows based

PS3 can recognise Fat32 or ext2. I am assuming you are saying that your file is greater than 4gb and that you transferred via an EXT HDD? I think by default the file system for the PS3 is in ext2 format. For external transfer via a HDD it is also possible to have a Fat32 file system that supports larger than 132gb volume sizes but I am not sure if they allow for more than the 4gb file limit. There are free extended Fat32 utils etc.

if you are using an external HDD then I suggest extended Fat32. Obviously transfer over a network makes it all irrelevant since the source and destination file systems do not come into play.

PS3 Media Server allows the PS3 to the NTFS volumes basically striped of all their permissions.

The PS3 internal hdd is not FAT32... rather some ext2 or ext3 mutation. If you transfered over network (local or downloaded) directly on the PS3, there is absolutely no problem with any 4gb limit.

Not sure whether anything other than Fat32 is supported for external USB hdds though, and for them Fat32's 4GB limit is pretty much a structural thing for the file system itself... don't think it's possible to store anything larger than 4Gb on that although I've heard of some mac app that automatically splits into parts when copying 4GB files to Fat32 (and then merges locally when reading), but that's a workaround, not a broken limitation.
