32-Bit File Access Requires MS-DOS 6.2 DoubleSpace (106248)

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.
