C enterprise is only one dish, because it is good security and performs well
So sometimes, we need another system disk to do something, such as a remote when you need a system disk with the past, this time, you can use this command subset to solve this problem.
Called mirrored virtual disk subst command, which can simplify many operations, such as a common file in a deep folder path, every time we want to manipulate these files must be a level along the path to the folder open, so the operation is very time-consuming operation [now I usually write a bat in the root directory, and then find that each time directory, run the bat. This path or recorded on a notepad posted each time to the address bar]. Of course, this command now know much more convenient. . . practice:
For example, we give the E drive under a folder testdir build a virtual disk F, you can use the command:
subst F: E: \ testdir
so you simply double-click the F directly to that of the directory we want. . .
Delete map:
subst F: / D
if mapped multiple folders, then it directly with subst View details. .
But these operations will disappear after the restart. . .
