SUMMARY

To use 32-bit file access (VFAT) with DoubleSpace, Microsoft Windows for Workgroups version 3.11 requires that you install MS-DOS 6.2 or later.

MORE INFORMATION

Windows for Workgroups 3.11 does not allow 32-bit file access on a system that has the DBLSPACE.BIN file from MS-DOS 6.0 loaded. MS-DOS 6.2 is required for compatibility with 32-bit file access.

If DBLSPACE.BIN from MS-DOS 6.0 is loaded in memory, the 32-bit file access option is disabled. If you are using MS-DOS 6.0 and do not have any compressed drives mounted but DBLSPACE.BIN is loaded in memory, 32-bit file access is still unavailable. You must unload DBLSPACE.BIN from memory to enable 32-bit file access.

NOTE: Microsoft recommends that you make a backup copy of your DBLSPACE.INI file before you use the following procedure.

To unload DBLSPACE.BIN, proceed as follows:

  1. Remove the system and hidden attributes from the DBLSPACE.INI file in the root directory of your startup drive by typing the following at the MS-DOS command prompt and then pressing ENTER:

    attrib -s -h -r c:\dblspace.ini

  2. Rename the DBLSPACE.INI file by typing the following at the MS-DOS command prompt and then pressing ENTER:

    ren c:\dblspace.ini dblspace.ino

  3. Restart your computer by pressing CTRL+ALT+DEL.

If you want to use any compressed drives on your system, you must rename the DBLSPACE.INO file to DBLSPACE.INI and restart your computer.

For more information on how DBLSPACE.BIN determines if it should remain in memory, query on the following words in the Microsoft Knowledge Base:

dblspace.bin and dblspace.ini and memory
