DOCUMENT:Q104947 20-NOV-1999 [msdos] TITLE :DoubleSpace Leaves ASPI4DOS.SYS and UPSI14.SYS on Host Drive PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.2,6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system versions 6.2, 6.22 ------------------------------------------------------------------------------- SUMMARY ======= 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. MS-DOS 6.2 DoubleSpace leaves the following files on the uncompressed host drive: ASPI4DOS.SYS USPI14.SYS MORE INFORMATION ================ DoubleSpace supports restartability during the compress and uncompress processes. If you are compressing or uncompressing a DoubleSpace- compressed drive and the process is interrupted (for example, there is a loss of power), MS-DOS restarts the DoubleSpace compress or uncompress process when the machine restarts. Machines that use ASPI4DOS.SYS or USPI14.SYS need to have these files available when the system restarts. To support these machines, DoubleSpace leaves the files on the uncompressed host drive. DoubleSpace knows to leave these files on the uncompressed host drive by reading the COPY= settings in the DBLSPACE.INF file. The COPY=[filename] entry specifies that the file should be copied to the compressed drive as well as left on the uncompressed drive. Additional query words: 6.20 UPSI14.SYS ====================================================================== Keywords : Technology : kbMSDOSSearch kbMSDOS622 kbMSDOS620 Version : MS-DOS:6.2,6.22 ============================================================================= THE INFORMATION PROVIDED IN THE MICROSOFT KNOWLEDGE BASE IS PROVIDED "AS IS" WITHOUT WARRANTY OF ANY KIND.
