DOCUMENT:Q117806 13-JUN-2001 [msdos] TITLE :DoubleSpace Conversion Kit: Description & How to Obtain PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.22 OPER/SYS: KEYWORDS:kbfile msdos kbgraphxlinkcritical ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system version 6.22 ------------------------------------------------------------------------------- SUMMARY ======= This article describes the Microsoft DoubleSpace Conversion Kit (DBLCONV.EXE) and how to obtain and install it. The DoubleSpace Conversion Kit enables you to convert DoubleSpace-compressed drives to DriveSpace format. DBLCONV.EXE is a self-extracting executable file that contains the following files: DRVSPACE.MR1 README.TXT SETUP.EXE DBLCDESC.TXT NOTE: If you installed MS-DOS 6.22 Step-Up, you should already have the DRVSPACE.MR1 file in your DOS directory and therefore do not need to obtain this conversion kit. MORE INFORMATION ================ Description ----------- The DoubleSpace Conversion Kit provides the DRVSPACE.MR1 file. If you used MS-DOS 6 or 6.2 before installing MS-DOS 6.22, the DRVSPACE.MR1 file enables MS-DOS to read data stored in the DoubleSpace compression format even if the DoubleSpace driver (DBLSPACE.BIN) is not loaded in memory. DRVSPACE.MR1 makes it possible to: - Convert DoubleSpace-compressed drives to DriveSpace format. - Use DriveSpace to mount and read DoubleSpace-compressed drives. - Use MS-DOS 6.22 ScanDisk to check and repair DoubleSpace-compressed drives and compressed volume files (CVFs), even if DBLSPACE.BIN is not loaded in memory. - Use MS-DOS 6.22 Backup for MS-DOS to restore backups created with MS-DOS 6 or 6.2 Backup for MS-DOS or Windows, even if DBLSPACE.BIN is not loaded in memory. IMPORTANT: DRVSPACE.MR1 works in conjunction with the MS-DOS DBLSPACE.BIN file. If you did not install MS-DOS 6.22 over MS-DOS 6.0 or 6.2, you do not have the DBLSPACE.BIN file. If you did not install MS-DOS 6.22 over MS-DOS 6.0 or 6.2, you can obtain the DBLSPACE.BIN file from online services. For information about obtain- ing the DBLSPACE.BIN file, please see the following article in the Microsoft Knowledge Base: Q148479 Cannot Restore DoubleSpace-Compressed Backup with MS-DOS 6.22 For information about converting DoubleSpace-compressed drives to DriveSpace format, type "help dblspace" (without the quotation marks) at the MS-DOS command prompt after you upgrade to MS-DOS 6.22, and then choose the Notes button.
