Summary:
When the MS-DOS versions 4.x DIR command is used with an optional switch before a target directory that is on a drive other than the current drive, DIR produces a directory listing of the current directory rather than of the target directory.
A side effect of this is that the current directory of the target drive is changed to the directory specified in the target parameter of DIR.
More Information:
This problem can be reproduced using the following commands (assuming a floppy disk is in drive A and a C:subdirectory exists on the hard disk):
Command Comments ——- ——–
a: Make A: the current drive.
cd c: Change to the root directory of C:.
dir c: Show a directory of the current C: directory (C:).
dir /w c:Attempt to show a wide directory of C:; you get A:.
dir c: Show a directory of the current C: directory (C:).
The last DIR C: command should produce a directory listing of the root directory of drive C, just as the first DIR C: command did; however, the current directory of drive C was implicitly changed by the DIR command, and the DIR command did not produce the proper directory listing.
Please note that the same command functions are expected when the /W option is placed after the target directory parameter.
Microsoft has confirmed this to be a problem in MS-DOS versions 4.0, 4.01, and 4.01a. This problem does not occur in later versions of MS-DOS.
