Remove JOIN Assignments in MS-DOS 6.22

In MS-DOS 6.22, the JOIN command allows users to link a disk drive to a directory on another drive, making the attached drive appear as a subdirectory. This guide explains how to disconnect these directory assignments using the command's built-in removal switch, restoring standard drive letters and independent directory structures in MS-DOS.

The Removal Command

To remove a directory assignment created by the JOIN command, run JOIN followed by the assigned drive letter and the /D (delete) switch.

JOIN drive: /D

• drive: specifies the drive letter that was previously joined to a directory.
• /D instructs MS-DOS to delete the specified join assignment.

Step-by-Step Example

1. Check Active Assignments:
   Before removing a mapping, view all current joins by typing JOIN without any parameters:

   JOIN

   If drive B: is joined to directory C:\DRIVEB, MS-DOS displays:

   B: => C:\DRIVEB

2. Delete the Join:
   To remove this assignment and restore standard access to drive B:, enter:

   JOIN B: /D

3. Verify Removal:
   Type JOIN again with no parameters. If no assignments remain, MS-DOS will return to the command prompt without listing any drives. Drive B: is now fully accessible as its own separate drive, and C:\DRIVEB reverts to a standard empty directory.
