DOS Join

An external command that assigns a drive to a directory. For example, if a program accesses files on C only, but you want it to use files on B, you can make the B drive appear to be a directory of C. Join creates the directory, but it must be off the root.

    join b: c:\bdrive  join B to C:\BDRIVE
    join b: /d         unjoin B
    join               display join status

Don't use Join with Assign, Subst, Backup, Chkdsk, Diskcomp, Diskcopy, Fdisk, Format, Label, Recover, Restore or Sys commands on a joined drive.

Join was eliminated in Windows 95.
