No-Frills Command Line Unzipper 1.05 is created to be a simple and high-quality utility which brings users the advantage of not requiring command switches. Commands are interpreted according to argument order. The first argument is the zip file, the second is the unarchive folder and the third and more are files to be unarchived. If the second argument is extension-less, it is interpreted as a folder.

Also note if no extension-less argument is provided in the second position the unzip folder is the current one. Several files to be unzipped can be placed in the 3rd, 4th, 5th etc arguments with a space as a separator (or 2nd, 3rd etc if no folder name is indicated). No-frills has some additional advantages over for example zlib based unzippers. It unzips Microsoft Office 2007 files without an added a zip extension. It excels at unzipping corrupted zip and Microsoft Office 2007 files without the specification of additional options.

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.
