I believe that PHP runs fine on 64-bit hardware, and uses 64-bit ints everywhere on that... So, in theory at least, just buying a 64-bit machine would "solve" your problem... Not that you necessarily *can* run out and buy a 64-bit machine, mind you. > I'm asking because I would like to perform operations on large files, and > > fillesize($filename) > > is returning an error, even when I use > > sprintf("%u", filesize($file)) > > as per the manual for filesize().

At least for THIS particular function, you could use exec("du $filename", ...) and then you'd have a string representation of the size, which you could then display or even manipulate with BC_MATH or that other new-fangled arbitrary precision mathematics PHP Module whose name I forget. This is a much less general solution, but may suffice for now. -- Like Music? http://l-i-e.com/artists.htm
