- Well, SpaceSaver would most certainly NOT help at all, although the compressed files
- are indeed smaller, they must be recompressed TO DISK before they are opened.
- (this actually why Space Saver does not suffer from the incompatabilities and
- behavioural oddities that AutoDoubler suffers from).
-
- AutoDoubler, because it decompresses into memory (read-protecting applications)
- it *can* be quicker to start applications if you have a fast CPU and a slow
- disk, but that is only a theory...
