Drive and Path Settings May Be Invalid After Uncompress PSS ID Number: Q104848 Article last modified on 11-02-1993 PSS database name: O_MSDOS



The information in this article applies to:
- Microsoft MS-DOS operating system version 6.2


After uncompressing a DoubleSpace-compressed drive, some applications may not be configured for the correct drive and path. This problem can occur when either of the following conditions exist:

  • You create a new DoubleSpace-compressed drive (instead of compressing an existing drive).


  • You have software installed on a DoubleSpace host drive.


When you uncompress a DoubleSpace-compressed drive, the drive letters revert back to their original settings. For example, if your DoubleSpace-compressed drive is C, your host drive is H, and you uncompress C, all your files will be on drive C. Applications that were on the uncompressed H drive will be on the uncompressed C drive. In a second example, if you create a new DoubleSpace-compressed drive (D) and install some software, when you uncompress D, the files will reside on drive C.

This change in drive letter location can cause problems for Windows- based applications and other applications that store drive information in configuration files.


Since many of the configuration settings are saved in application- specific files, MS-DOS cannot make the changes for you.

To work around this problem, you must reconfigure your application(s). It’s a good idea to check the following files for erroneous drive references:


For more information on reconfiguring a specific application after uncompressing a DoubleSpace-compressed drive, check with the application vendor.
