The information in this article applies to:
• Microsoft MS-DOS operating system 6.0
• Microsoft MS-DOS operating system 6.2
• Microsoft MS-DOS operating system 6.22
This article was previously published under Q96130
This information applies to both Microsoft DoubleSpace and Microsoft
DriveSpace. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands
If you have DBLSPACE.BIN in the root directory of your startup drive
(usually C) but you do not have a compressed volume file (CVF),
DBLSPACE.BIN still loads in memory.
After DBLSPACE.BIN loads in memory, it searches for the DBLSPACE.INI
• If DBLSPACE.INI is found, DBLSPACE.BIN remains in memory and
continues the boot process by loading IO.SYS in memory. (It doesn't
matter whether the DBLSPACE.INI file is valid.)
• If the DBLSPACE.INI file is not found, DBLSPACE.BIN does not remain
loaded in memory.
NOTE: The DBLSPACE.SYS command in the CONFIG.SYS file does not affect
If you attempt to load DBLSPACE.SYS in the CONFIG.SYS file when
DBLSPACE.BIN is not loaded into memory, the following error message is
To correct this problem, remove the line in the CONFIG.SYS that loads
DBLSPACE.SYS or assure that DBLSPACE.BIN remains in memory on startup.
