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.) Syntax DRVSPACE /UNCOMPRESS drive: Parameter drive: Specifies the drive you want to uncompress. Switch /UNCOMPRESS Uncompresses the specified drive.
