It copies files (and folders) from anywhere to anywhere else.
Because it can copy invisible files. :-)
Run it, pick the appropriate command from the File menu (for copying files or folders), pick the original file/folder, pick the destination, and sit back and wait. If you hear a beep something went wrong.
If you don't like it, don't use it. Even better, the source is on the website; fix it yourself!
