Re: MD5 of a file is different on different computers?

No joining function/software was used before checking the MD5, so it rules that out.

Some computers are running NTFS, some are Mac OS Extended

All the dates/times are showing as the same.

How do I check 32bit vs 64bit?

Thanks for trying to help.. I'm surprised by the lack of replies on this thread, I would have thought that discovering that a tried and tested proven technology is in fact seriously flawed, might be interesting to a lot of people!
