Not necessarily under the 32bit variants of Windows - I am not sure about Win95 (I never touch it if I can possibly avoid it) but WinNT3.51 and 4. both allow files larger than 2GB, and the Win32 native file operations use 64bit file pointers. I have no idea what would happen if you tried to access these with regular file ops - my guess is that sequential read would work but tell() / seek() would get wrapped.
