In a nutshell, DriveSpace 3 takes care of all of DoubleSpace's deficiencies and adds several new features that make it worth the effort to install it.
Rather than using DriveSpace 3 to compress my entire hard disk, I used the software to create another drive on my hard disk, the D: drive.
There is also a "compression agent" program included with DriveSpace 3.
You can fine-tune DriveSpace 3 to provide whatever balance of space saving versus read-write speed that you want.
0 provides more available disk space than other technologies, and users can easily upgrade to PC DOS 7 from MS-DOS DoubleSpace and DriveSpace
, IBM SuperStor/DS and earlier Stacker versions without decompressing existing files.
