Re: 32-bit file size limit?

On Tue, 27 Jan 2009 18:52:32 +1100, Jim Adamthwaite typed this message:

System: Suse 11.1 (32 bit).

I notice that v10.3 & v11.1 will not copy files longer than 4GB (e.g. a
DVD .iso file of 4.5 GBytes).
.
I can download it from OpenSuse ok, but cannot copy it either to another
directory or over the LAN to another PC.

I am guessing that the C file-size tye definition is an unsigned 32-bit
number, so any functions like seek or setting file size must fail on a
longer file.

Question: do the 64-bit versions of Linux define file size as a larger
format number such as a quad int?

If all the foregoing is correct, I suspect we are all nudging the
boundary and will need to migrate to 64 bits fairly soon.

Sounds like the other PC is a Fat32 file system. Change the Fat32 file
system to an NTFS file system and your size limitation goes away.

A couple of years ago it drove me crazy until I realized I the FAT
limitation.
