Those individuals with sizable (or not so-sizable) music collections may wish to take a look at the Picard Tagger application. The application allows users to create album-oriented tags that will work across different platforms, and it will also help them to create a more sophisticated way of accessing and organizing their music files. The site for this application also contains complete documentation and some video demonstrations of how the application can be used. This version is compatible with computers running Linux, Mac OS X 10.3 and newer, and Windows 98 and newer. [KMG]

If you've ever found yourself in a pickle after accidentally placing some needed files in the recycle bin, you'll appreciate this helpful application. Created by Brian Kato, the Restoration application effectively restores files which have been deleted from the recycle bin by mistake. Conversely, the program has another function that makes it almost impossible to restore all deleted files. This version is compatible with computers running Windows 98 and newer. [KMG]
