Installing DiskDoubler is easy. Simply double-click on Salient's installer application and it automatically installs the DiskDoubler files, including the application, the extension, and the help file

Installing SuperDisk! is equally as easy as installing DiskDoubler. If you're running System 6.0.x, simply drag the SuperDisk! Control Panel into your System Folder

Although DiskDoubler and SuperDisk! both serve the same function, how they approach the task differs. When you compress a DiskDoubler file, you'll know it's compressed right away - the icon for the document or application that you just compressed turns into a DiskDoubler icon

(aka "The Bottom Line") One of the fundamental problems with compression is a trade-off between time versus space. If you spend more time trying to compress a document, you can usually do a better job
