SUBST
SUBST is used for substituting paths on physical and logical drives as virtual drives.Generally C# developers uses SUBST to create "Z:" drives to map the binaries of the application(Web/ Windows) at single location.
So when code is moved on other machine, you can keep binaries in any of the folder and just SUBST it to "Z:". So this removes the need to re add all references in the application.
