Explanation:
Assign a mount point folder path to a drive

You can use Disk Management to assign a mount-point folder path (rather than a drive letter) to the drive. Mount-point folder paths are available only on empty folders on basic or dynamic NTFS volumes.

Backup Operator or Administrator is the minimum membership required.

Assigning a mount-point folder path to a drive
1. In Disk Manager, right-click the partition or volume where you want to assign the mount-point folder path, and then click Change Drive Letter and Paths.
2. Do one of the following:
* To assign a mount-point folder path, click Add. Click Mount in the following empty NTFS folder, type the path to an empty folder on an NTFS volume, or click Browse to locate it.
* To remove the mount-point folder path, click it and then click Remove.
