I think most would think that copying a file carries some risk but in over 2 decades this has never been a concern of mine since a file copy does just that. It moves/copies a file from one place to another.

Since the file is never opened with its corresponding application or "run" then the risk is about as low as it gets.

Once I have the files on a memory stick or CD I can scan it with the usual antivirus and such.
