Yes!

Thanks a lot, "md5_file" suits perfectly well my needs.
I've read that 'exec'ing the md5 command is faster... I'll see when performance on large files will become an issue.

Thanks again,

You could use "md5_file" for this. Something like:

function files_identical($path1, $path2) {

return (md5_file($path1) == md5_file($path2));

}

Doing a diff on the files would make absolutely certain - an md5
checksum is not.
