FastTips: MS-DOS 6.2 DoubleSpace Uncompress Q&A
Last reviewed: November 23, 1994

The information in this article applies to:


 * Microsoft MS-DOS operating system versions 6.2, 6.22

IMPORTANT: Although the text in the following questions and answers specifically refers to MS-DOS 6.2 DoubleSpace, the information also applies to MS-DOS 6.22 DriveSpace. If you have MS-DOS 6.22, substitute DRVSPACE for any DBLSPACE commands.

1. Q. When I try to uncompress my DoubleSpace drive, I get an error message telling me I have a duplicate filename on my DoubleSpace- compressed drive and host drive. I cannot find any duplicate files or directories on my DoubleSpace-compressed drive and my host drive. What can I do to correct this?

A. If you cannot identify the duplicate filename, the file or     directory may be hidden. Use the TYPE command or MS-DOS Editor to view the DBLSPACE.LOG file that is located on your host drive. Once you have determined the duplicate filename(s), use the DIR /A command to look for the file(s). You can use the ATTRIB command to remove the hidden or system attribute from the file(s) and then rename or delete the file(s).

If DBLSPACE.LOG lists a directory, you can use the MOVE command to rename the directory. For example, type "move h:\sentry     h:\xsentry" (without the quotation marks) at the MS-DOS command prompt and press ENTER.

2. Q. I'm trying to uncompress my drive but DoubleSpace tells me there isn't enough space to uncompress my data, what can I do?

A. When you uncompress your DoubleSpace-compressed drive, you are taking compressed data and expanding it. If your drive was nearly full when you compressed it and you have since added new software or documents, you may have more data than will fit on     an uncompressed drive.

If you must remove DoubleSpace, you must either remove some files before you uncompress your drive or purchase a larger hard disk drive.

NOTE: DoubleSpace is very conservative when estimating the free space required to uncompress a floppy disk. DoubleSpace may require you to free some space even when it seems the data will fit on the uncompressed disk.
