Maximum file size on IA32

[Honen, Oren]

Hi, I’m using a graphical application on 32bit RH Linux. The user saved files are getting larger and larger. Currently the largest file is at about 2GB . The vendor of the application says that larger files will require the 64bit version which he doesn’t have on Linux. The files are saved on NFS. I know changing ext2 block size can enable you to save larger files than 2G so their answer doesn’t sound reasonable. Beside, even if they had the entire file in ( virtual ) memory, they needed to have their code in it too and I’m not sure they had the place. This made me think that they don’t read the entire file to memory, what returns the question to the filesystem maximum size ability. 1. Does 32bit systems force files <=2GB ? 2. Does NFS has that limit ? 3. Since 32bit span is 4G ( 2^32 ) why do I always hear about 2G limitations ( Virtual memory & files so far )   Thanks Oren Honen.
