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


You receive the following error message if you attempt to create a new DoubleSpace drive by typing DBLSPACE /COMPRESS on a drive that has more than 512 megabytes (MB) of data:

Drive C contains too much data to compress. To compress a drive, it cannot contain more than 512 MB of data.
If you type DBLSPACE under the same conditions, you receive the following error message:

DoubleSpace did not find any drives that can be compressed. To compress a disk, first make sure it is formatted and does not contain over 512 MB of data.


To work around this problem, you can delete unnecessary files so that you have less than 512 MB of data or follow the procedure outlined below.


To work around this problem without reducing the volume of data on your hard drive, manually create a new DoubleSpace drive and move data to the new compressed drive. Once the uncompressed drive contains less than 512 MB of data, you can then compress that drive.

To manually create a new DoubleSpace drive:
    Copy the DBLSPACE.BIN file from the DOS directory to the root directory. For example, if the DOS directory is on drive C, type the following at the MS-DOS command prompt and then press ENTER:

    copy c:\dos\dblspace.bin c:\

    Set the file attributes on DBLSPACE.BIN to read-only, hidden, and system. To do this, use the ATTRIB command as in the following example:

    attrib c:\dblspace.bin +r +s +h

    Create a DBLSPACE.INI file using the COPY CON command. To do this, type the following at the MS-DOS command prompt and then press ENTER:

    copy con c:\dblspace.ini

    Press ENTER twice.
    Press CTRL+Z and then press ENTER to close and save the file.
    Restart your computer by pressing CTRL+ALT+DEL.
    Run DoubleSpace by typing DBLSPACE at the MS-DOS command prompt and pressing ENTER.
    From the Tools menu, choose Options.
    Increase the "Last drive reserved for DoubleSpace's use:" setting five letters. For example, if the current letter for Last Drive Reserved For DoubleSpace's Use is D, increase that setting to I.
    Press ENTER to save your changes and then press ENTER when you are prompted to "Restart Your Computer Now."

    After the computer has restarted, you should have a complete DBLSPACE.INI file.
    You can now run DoubleSpace and create a new compressed drive. To do this, type DBLSPACE at the MS-DOS command prompt, press ENTER, and then choose Create New Drive from the Compress menu.
After you create the new DoubleSpace drive, you can move data from your uncompressed drive to your new drive. If you reduce the data on the uncompressed drive to less than 512 MB, you can run DoubleSpace to compress that drive.

NOTE: If you move Microsoft Windows or Windows-based applications to the new drive, adjust your .INI files and run Registration Editor to reflect the new drive location of your files. If you move system files or network files to the compressed drive, adjust your CONFIG.SYS and AUTOEXEC.BAT file accordingly.
