UNINSTALL and DELOLDOS Don't Remove Directories (96937)

If you use a directory name other than the default directory name for
MS-DOS (C:\DOS), the commands UNINSTALL and DELOLDOS may have difficulty
finding and removing the appropriate directories. Also, MS-DOS Setup may
not put your previous MS-DOS files in the appropriate OLD_DOS.<X> directory
(where <X> is a number based on the number of OLD_DOS directories that have
not been removed).
Microsoft has confirmed this to be a problem in MS-DOS version 6.0, 6.2,
and 6.21. We are researching this problem and will post new information
here in the Microsoft Knowledge Base as it becomes available.
If you run DELOLDOS, the OLD_DOS.1 directory is removed; however, the
MSDOS5 directory, which contains all the old MS-DOS files, is not.
Your directory structure appears as follows:
c:\msdos5 (still contains old MS-DOS files)
c:\msdos6 (contains new MS-DOS files)
If you run UNINSTALL, OLD_DOS.1 is removed, along with all the files
in MSDOS6; however, the MSDOS6 directory is not removed. Your
directory structure appears as follows:
c:\msdos5 (contains old MS-DOS files)
c:\msdos6 (contains no files)
All these commands (SETUP, DELOLDOS, and UNINSTALL) correctly manage
the MS-DOS PATH variable and do not jeopardize any operating system
functionality. The only problem is in the proper removal and creation
of certain directories.
