Come to think of it, generating a checksum for your file is probably much faster than the transfer rates of your hard-drive.

I need to find a way to quickly check if 2 files are different.  I was thinking maybe generating a checksum value from the file's data but that would probably be too slow.

I want to do this because I frequently copy many files from a src directory to a dest directory/console and this takes a while. 

Thanks,
