subst

The command line tool "subst" in Windows is used to assign a drive letter to a specific path on the local file system. It allows users to create a virtual drive letter that represents a specific folder or directory on their computer. This can be helpful when users want to access a specific path quickly without navigating through the entire directory structure. The subst command is followed by the name of the drive to be created and the path that it represents. The virtual drive created using subst will act just like a physical drive, allowing users to perform all the usual operations such as opening, copying, and deleting files. To remove the virtual drive, the "subst" command is used with the drive letter followed by /D parameter. The subst command can be quite useful for organizing and managing files efficiently, especially for frequently accessed directories.
