Liberer is a simple utility to remove or add files from/to your library (either your home or the all-users one). It has user friendly interface even for people who don't know anything about computers (at least I think so). Everything is icon-illustrated and every library folder has a description of what is that folder used for. What's New: Version 1.3: [Change and Fix] To fix the compatibility with MacOS X 10.2, I had to "demetalize" the environment. If you like the metal environment more than this one, send me an e-mail. [New] Added help [New] You can drop files on the list box now |
