This information applies to both Microsoft DoubleSpace and Microsoft DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames.


When you use the DBLSPACE /UNCOMPRESS command to uncompress the last mounted compressed drive, DoubleSpace may not remove the DBLSPACE.SYS line from the CONFIG.SYS file.


This problem occurs when any portion of the DBLSPACE.SYS line contains one or more lowercase letters. For example, the following line would not be removed because of the lowercase letter e:



To work around this problem, edit the CONFIG.SYS file and manually remove the DBLSPACE.SYS line.


The DBLSPACE.SYS line contains lowercase characters only if it has been modified by a user. If this line remains in the CONFIG.SYS file, DoubleSpace does not generate an error message or alert the user of any problems when you boot. Although it is present in the CONFIG.SYS file, the DoubleSpace driver does not load into memory because DBLSPACE.BIN has been removed from the root directory of the boot drive.
