SUBST – command to easily from folder create virtual drive

It is possible to map a folder to a drive letter. This old DOS function does not change for a long time, and it is easy to manage. Windows added some new options, no to command itself, but to way how it can be used.

To map folder to virtual drive:

SUBST [driveletter:] [folderpath]

Example:

SUBST F: c:\temp

or

SUBST F: “c:\My Folder\My Subfolder”

If the path contains spaces, enclose the it in quotes.

To remove existing mapping:

SUBST [driveletter:] /D

Example

SUBST F: /D

To get a help:

SUBST /?
