DRVSPACE /UNCOMPRESS 
Uncompresses a drive that was compressed by using DriveSpace. When you      
uncompress the last mounted drive, the /UNCOMPRESS switch also removes
DRVSPACE.BIN from memory. (DRVSPACE.BIN is the portion of MS-DOS that
provides access to compressed drives. It uses about 50K of memory.)
