input: [Option] -d dir [Explanation] 
output: Copy restored mp3 files to this directory. Since restoring tags always involves copying the whole mp3 file you can save time here. If you have your mp3 files on a cd and want to restore them to the hard drive and restore their tags you can do this at the same time. In this case the file listing of mp3 files would be the contents of the CD and the desired hard drive place would be in the '-d' parameter.
