Clusters takes advantage of the file compression technology built into Mac OS X to help you regain space, keep your system tidy and launch your files faster. Clusters is a background and transparent file compressor: Mac OS and your apps will use compressed files without having to expand them first - they will just take less disk space and load faster.

How does it work? Just select some folders to compress and Clusters will silently work in the background, using your system spare resources to increase free space and make file access faster. Clusters will watch for changes in the folders you configure: for example, set Clusters to work on your Applications folder to automatically compress any new apps you install, thus having them launch faster.

Grab Clusters now and see for yourself. The demo version will allow you to gain up to 50MB of space.
