Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

                                  DBLSPACE
 
Configures drives that were compressed by using DoubleSpace, the integrated
compression that was included with MS-DOS 6 and MS-DOS 6.2.
 
Note:  MS-DOS 6.22 does not include DoubleSpace compression. Instead, MS-DOS
       6.22 includes DriveSpace compression, which appears similar to
       DoubleSpace but which stores compressed information in a different
       format.
 
If you currently use DoubleSpace, you can continue to do so with MS-DOS
6.22. For more information about using DoubleSpace with MS-DOS 6.22, see
<Notes>.
 
If you currently use DoubleSpace and want to use DriveSpace instead, you can
convert your system to DriveSpace. For more information, see "Converting
from DoubleSpace to DriveSpace" in <Notes>.
 
If you do not currently use DoubleSpace and want to compress your drives,
use DriveSpace. To do this, type DRVSPACE at the command prompt. For more
information, see <DRVSPACE>, or see "Freeing Disk Space by Using DriveSpace"
in your Microsoft MS-DOS User's Guide or Microsoft MS-DOS User's Guide
Addendum.
 
Syntax
 
When you issue the DBLSPACE command by itself, the DoubleSpace program
starts. You can use this program to create and manage DoubleSpace compressed
drives.
 
If you add switches or parameters to the DBLSPACE command, MS-DOS carries
out the requested task without starting the DoubleSpace program. The command
syntax differs from task to task.
 
Note:  The switches and parameters for the DBLSPACE command are identical to
       those of the DRVSPACE command. MS-DOS 6.22 Help describes only the
       command syntax for DRVSPACE. If you use DoubleSpace instead, refer to
       the Help for the corresponding DRVSPACE command, and just type
       DBLSPACE instead of DRVSPACE when issuing the command.
 
You can use the DBLSPACE command to perform the following tasks:
 
♦  Compress a hard disk drive or floppy disk. For more information, see
   <DRVSPACE /COMPRESS>.
 
♦  Create a new compressed drive in the free space on an existing drive. For
   more information, see <DRVSPACE /CREATE>.
 
♦  Defragment a compressed drive. For more information, see
   <DRVSPACE /DEFRAGMENT>.
 
♦  Delete a compressed drive. For more information, see <DRVSPACE /DELETE>.
 
♦  Format a compressed drive. For more information, see <DRVSPACE /FORMAT>.
 
♦  Display information about a compressed drive. For more information, see
   <DRVSPACE /INFO>.
 
♦  Display a list of the drives on your computer. The list includes
   compressed and uncompressed hard disk drives, floppy disk drives, and
   other removable-media drives. It does not include network drives. For
   more information, see <DRVSPACE /LIST>.
 
♦  Mount a compressed volume file (CVF). When DoubleSpace mounts a CVF, it
   assigns it a drive letter; you can then use the files that CVF contains.
   For more information, see <DRVSPACE /MOUNT>.
 
♦  Change the estimated compression ratio of a compressed drive. For more
   information, see <DRVSPACE /RATIO>.
 
♦  Change the size of a compressed drive. For more information, see
   <DRVSPACE /SIZE>.
 
♦  Uncompress a compressed drive. For more information, see
   <DRVSPACE /UNCOMPRESS>.
 
♦  Unmount a compressed drive. For more information, see
   <DRVSPACE /UNMOUNT>.
 
♦  Change the settings in your DRVSPACE.INI file. For more information, see
   <DRVSPACE.INI>.
