SpaceSaver invisibly compresses your files and folders so you have more disk space. When you use a compressed file, SpaceSaver transparently expands it; when you're finished, it automatically recompresses it - so there's no need to change the way you work with your Macintosh.
SpaceSaver compresses files and folders on demand, to an average of half their original size. Some graphic files compress to one-twentieth their original size.
SpaceSaver automatically compresses any file that hasn't been modified for a specified length of time - you get to choose.
SpaceSaver is fully StuffIt Deluxe compatible, safe to use, and fully user-configurable.
