Type: External (3.1 and later)
Syntax:
JOIN d: [d:path]
JOIN d: [/D]
Purpose: Allows access to the directory structure and files of a
drive
through a directory on a different drive. (In DOS Version 6, this
program is
stored on the DOS supplemental disk.)
Discussion
After joining a drive to a directory, the files stored on the joined
drives can
be accessed as if they were on the specified directory.
Attempts to access the joined drive will result in the display of the
error message
Invalid drive specification
If you try to join a directory containing files, the program will display
the error message
Directory not empty
You cannot join the current directory. Also, you cannot join to a
directory
that is more than one level below a root directory or to the root
directory itself.
If the directory you specify in the second parameter does not exist, DOS
will create it. If the directory does exist, it must be empty.
For more information on JOIN and other hard disk commands, see Chapter 3,
Using Fixed Disks, in the downloadable
book DOS the Easy Way .
Option
/D - Used to disconnect a joined drive.
Examples
To join drive B to the directory FILES on drive A, enter
join b: a:\files
If you now ask for a directory of A:\FILES, the files stored on drive B
will be displayed.
After entering this command, attempts to access drive B will result in
the error message
Invalid drive specification
