SYMPTOMS
========

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).

  -or-

 - You have software installed on a DoubleSpace host drive.

CAUSE
=====

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.

RESOLUTION
==========

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:

   AUTOEXEC.BAT
   CONFIG.SYS
   SYSTEM.INI
   WIN.INI
   PROGMAN.INI
   <APPNAME>.INI

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