No, the source files will always be unaffected. If you specify the source and destination the wrong way round or specify the wrong destination with the /MIR option the results can be catastrophic. > Now, if I add files only to the source then it seems like either > function will do the same thing. Is that correct? Yes, provided you only add files. I occasionally move some files around, in this case the /MIR option will delete the original copy and recopy the moved files to their new location. > If I change some genre tags on the source, will both mirror and backup > make those changes on the destination? How about MusicMagic/IP codes > saved to the track files? Yes, provided the file timestamp is updated robocopy should see the changes. However some tag editors, such as Tag & Rename, have an option not to update the timestamp. In this case robocopy would not be aware that the file has changed. I've never used MusicMagic so I don't know if it updates or preserves the files timestamp.
