How to mount a virtual drive letter from a folder

For example of a drive letter, I’ll use D:! For example of a folder, I’ll use C:\D\!

If you don’t have the possibility to create a D: partition, you can easily solve it by mounting any kind of folder as a virtual D: partition!

For example, you could use a folder like C:\D\ as D:!

All you need to do is to create these two .bat files and add them inside C:\D\!

mount_d.bat
```
  @cd %~dp0
  @subst d: .
  @pause
```
Run this file if you want to mount the current folder as D:
unmount_d.bat
```
  @subst d: /D
  @pause
```
Run this file if you want to unmount the virtualized D:

Note: if you want to see the virtual mounted D: folder in the admin-runned programs (e.g. PS/3dsMax), run the mount_d.bat as admin as well! (twice: one normal as user, one as admin)

Note2: if you have another component like a CD/DVD burner as D:, you can simply switch it very easily in few seconds! Google it
