1. Q. Why does DoubleSpace create a drive identified by the letter H
when I have drives A, B, and C only?

A. To avoid conflicts with existing drives, DoubleSpace examines
the existing drive assignments during installation to find the
highest drive letter currently in use. It then skips the next
four letters and assigns the fifth letter to the new
DoubleSpace drive.

For example, if your computer has two floppy disk drives (A and
B) and a hard disk drive (C), DoubleSpace locates the highest
letter (C); skips drive letters D, E, F, and G; and then
assigns drive letter H for its own use.

For more information, refer to the "Freeing Disk Space" chapter
in the "Microsoft MS-DOS 6 User's Guide."

2. Q. I am currently using a third-party disk-compression software
package and now want to convert to DoubleSpace. How can I do
this?

A. To convert to a DoubleSpace drive, use the following steps:

1. Install the MS-DOS 6 Upgrade if you haven't already done so.

2. Back up your program and data files on all drives using
Microsoft Backup or a third-party utility.

3. Create a bootable MS-DOS floppy disk. To do this, insert the
original MS-DOS 6 Setup Disk 1 in either drive A or drive B,
type the following command, and then press ENTER

drive:setup /f

where "drive" is the floppy disk drive containing Setup Disk
1.

Important: After you type the above command and Setup
prompts you to insert a disk to create the startup floppy
disk, you MUST create that disk in drive A. Also, be sure
that you choose to install on drive A.

4. Verify that the disk you have just created is bootable by
inserting the disk in drive A and pressing CTRL+ALT+DEL. If
your system starts up, continue with the next step. If it
does not, reboot from your hard disk and repeat step 3 until
you have created a bootable floppy disk.

5. Format the drive with the compressed volume file (CVF). To
do this, type the following command at the A: prompt and
then press ENTER

format drive:

where "drive" is the floppy disk drive containing the CVF.

Note: If you are formatting drive C, use the /s switch with
the format command to make the hard disk bootable.

6. If you formatted a drive other than C, skip to step 7. If
you formatted drive C, you must reinstall the MS-DOS 6
Upgrade. To do this, insert Setup Disk 1 in drive A or drive
B, type the following command, and then press ENTER

drive:setup

where "drive" is the floppy disk drive containing Setup Disk
1.

Follow the steps on the screen to install the MS-DOS 6
Upgrade.

Note: If you used Microsoft Backup for MS-DOS to back up
your compressed drive, be sure to reinstall Backup for MS-
DOS when Setup prompts you to do so. (You need this program
to restore your backup disks.)

7. Install DoubleSpace. To do this, type "dblspace" at the MS-
DOS command prompt, press ENTER, and then follow the steps
on the screen.

Note: For more information on DoubleSpace, refer to the
"Freeing Disk Space" chapter in the "Microsoft MS-DOS 6
User's Guide" or type "help dblspace" (without the
quotation marks) at the MS-DOS command prompt and press
ENTER. For more information on Microsoft Backup, refer to
the "Managing Your System" chapter in the "Microsoft MS-DOS
6 User's Guide."

8. Restore the files from your backup disks by using Microsoft
Backup or your third-party backup utility. If you are using
a third-party backup utility, you must install the software
onto the hard disk. Refer to the manufacturer's
documentation for the procedure to do this.

3. Q. I installed DoubleSpace and now each time I enter Microsoft
Windows I receive the error "Corrupt Swapfile Warning." I have
set up my permanent swap file many times, but I continue to
receive this error. How can I correct this problem?

A. In this case, the error "Corrupt Swapfile Warning" probably
means your permanent swap file is being created on a
DoubleSpace compressed volume. Windows cannot create a
permanent swap file on a compressed volume. To correct this
problem, set the permanent swap file to a noncompressed drive.

Windows contains code to detect and avoid compressed volumes
created with third-party software. However, Windows cannot
detect compressed volumes created with DoubleSpace because
Windows' release predates the release of DoubleSpace.

For more information, refer to the "Freeing Disk Space" chapter
in the "Microsoft MS-DOS 6 User's Guide," or type "help
dblspace" (without the quotation marks) at the MS-DOS command
prompt and press ENTER.

4. Q. I am trying to run Windows 3.0 in real mode so that I can
change my permanent swap file with SWAPFILE.EXE. Every time I
try, I receive the error message "Unsupported DOS version;
upgrade to DOS version 3.1 or higher." What causes this error?

A. This is an incorrect message. To correct this problem, run the
SPATCH.BAT file, which is located on your original MS-DOS 6
Upgrade disks.

  1. Very nice! Thank you for this wonderful archive. I wonder why I found it only now. Long live the BBS file archives!

  2. This is so awesome! 😀 I’d be cool if you could download an entire archive of this at once, though.

  3. But one thing that puzzles me is the “mtswslnkmcjklsdlsbdmMICROSOFT” string. There is an article about it here. It is definitely worth a read: http://www.os2museum.com/wp/mtswslnk/
