DOCUMENT:Q91728 21-NOV-1999 [msdos] TITLE :MS-DOS 6 DoubleSpace Files and Functions PRODUCT :Microsoft Disk Operating System PROD/VER:MS-DOS:6.0,6.2,6.21,6.22 OPER/SYS: KEYWORDS: ====================================================================== ------------------------------------------------------------------------------- The information in this article applies to: - Microsoft MS-DOS operating system versions 6.0, 6.2, 6.21, 6.22 ------------------------------------------------------------------------------- SUMMARY ======= This article contains a list of DoubleSpace files and their functions. For MS-DOS 6.22, use DRVSPACE in place of DBLSPACE for commands and filenames. Filename Function ---------------------------------------------------------------------- DBLSPACE.BIN Main DoubleSpace Component DBLSPACE.EXE For creation or modification of a DoubleSpace drive DBLSPACE.HLP DoubleSpace online help file DBLSPACE.INF DoubleSpace Setup information file DBLSPACE.INI DoubleSpace information file DBLSPACE.WIN Used to keep track of Windows during DoubleSpace installation DBLSPACE.SYS Allows MS-DOS to load DoubleSpace device driver high DBLSPACE.00x Actual DoubleSpace drive stored as a file MORE INFORMATION ================ For definitions of terms used in this article, please see the DoubleSpace Help. DBLSPACE.BIN ------------ MS-DOS uses the DBLSPACE.BIN component to mount the compressed volume file so you can access the files on your compressed drive. This file loads automatically if it is in the root directory of the startup disk (no device= line is needed). If you want to load DBLSPACE.BIN into upper memory, see the DBLSPACE.SYS section of this article. DBLSPACE.EXE ------------ This file allows you to mount, create or modify DoubleSpace drives. DoubleSpace accepts the following parameters: DBLSPACE /CHKDSK [/F] [drive:] DBLSPACE /COMPRESS drive: [/F] [/NEWDRIVE=drive2:] [/RESERVE=size] DBLSPACE /CREATE drive: [/NEWDRIVE=drive2:] [/SIZE=size | /RESERVE=size] DBLSPACE /DEFRAGMENT [/F] [drive:] DBLSPACE /DELETE drive: DBLSPACE /FORMAT drive: DBLSPACE [/INFO] drive: DBLSPACE /LIST DBLSPACE /MOUNT[=sss] [drive:] [/NEWDRIVE=drive2:] DBLSPACE /RATIO[=r.r] [drive: | /ALL] DBLSPACE /SIZE[=size | /RESERVE=size] [drive:] DBLSPACE /UNMOUNT [drive:] For more information about DoubleSpace command-line options, type "HELP DBLSPACE" (without the quotation marks) or "HELP DBLSPACE /switchname" (without the quotation marks) (where /switchname is the name of the switch about which you want more information) at the command prompt. DBLSPACE.HLP ------------ This file contains help on DoubleSpace. To access this file, run DoubleSpace and choose Contents or Index from the Help menu. DBLSPACE.INF ------------ The DoubleSpace Setup information file is helpful when creating a new DoubleSpace drive, but it is not required. Commands under the [SpecialFiles] section indicate actions to be taken for specific files; the possible actions are COPY=, IGNORE= and MOVE=. Without a path, any file of that name will match; wild cards (?, *) are acceptable. Programs under the [CopyFiles] section are optional utilities that are left on the original boot drive if there is enough room. Programs under the [dangerous] section will be remarked out using the REM command from CONFIG.SYS file during DoubleSpace Setup but will not be remarked after Setup has completed. Programs under the [prior] section will have DEVICEHIGH=DBLSPACE.SYS placed ABOVE them in the CONFIG.SYS file. DBLSPACE.INI ------------ This file is used by DoubleSpace to mount the compressed volume and swap drive letters. The file contains the following settings: MaxRemovableDrives= FirstDrive= LastDrive= MaxFileFragments= ActivateDrive= DBLSPACE.WIN ------------ This is a temporary file that DBLSPACE.BIN generates to keep track of windows information when a drive is compressed. It should automatically be deleted after DBLSPACE.BIN completes the compression of the existing drive. DBLSPACE.SYS ------------ The DBLSPACE.SYS device driver does not provide access to the compressed drives, but it does provide the following functionality: - Allows DBLSPACE.BIN to be loaded high (using the devicehigh command) - Moves DBLSPACE.BIN from the top of conventional memory to the bottom (as device drivers load). This can eliminate conflicts with programs that require access to the top of conventional memory. DBLSPACE.00x ------------ A compressed drive is not a real disk drive, although it appears that way to most programs. Instead, a compressed drive exists on your disk as a hidden file called a compressed volume file (CVF). DBLSPACE.00x is the compressed volume file.
