Zip Contents Renamer renames the CDG and MP3 file inside a ZIP file to match the name of the ZIP file, allowing your MP3+G collection to be better organized. This is also much quicker than unzipping and renaming both files. An added feature is that ZIP file comments are stripped from the file automatically. For example, suppose you decide to change the naming format of your karaoke songs from Artist - Song - Disc to Disc - Artist - Song. just changing the file name of the ZP file may cause some software karaoke players to crash. By renaming the CDG and MP3 file to match the name of the ZIP file, you can avoid this potential problem.
