Mac Mini Invisible File Problem I've got an issue where after moving a file from the desktop a shared location (mac mini) the file doesn't appear. 

After duplicating the file, both the copy and the original file appear so it's not a permissions issue. Is there anything that could be causing it to ghost like that?

Both Mac and the mac mini are Mavericks 10.9.5
When you are dragging the file, do you see a small green plus sign? If you don't see this, it means that you are going to cut and paste the file, but if you can see the green plus sign it means you are going to duplicate the file into another location. By holding the option key, you can force duplication, and you can see the green plus sign appears.
