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.
