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.

You install DoubleSpace and one or more of your MS-DOS-based applications no longer runs.


The application(s) may be using a copy-protection scheme or may be looking for files that were left on the host drive.


If your application does not run after you install DoubleSpace, do the following:

    If the application uses a copy-protection scheme, contact the application vendor for information on how to make it work with DoubleSpace.
    Check the host drive for application files that were not transferred to the DoubleSpace volume by using the following steps:

      To determine your host drive, type dblspace /list at the MS-DOS command prompt and then press ENTER.
      At the MS-DOS command prompt, change to the host drive (for example, drive H).
      Change to the application directory (if one exists). For example, type cd appdir at the MS-DOS command prompt and then press ENTER.
      Use the DIR command with the /A and /S parameters to search for any files left in the directory. For example, type dir /a /s at the MS-DOS command prompt and then press ENTER.
      If any files are left in the applications directory, copy them to the DoubleSpace volume. For example, type the following at the MS-DOS command prompt and then press ENTER:

      copy h:\appdir\file.exe c:\appdir\file.exe
