Mounting a drive is a phrase commonly used to describe an advanced disk management technique that's often used in large organizations. A mounted drive is a partition that's mapped to an empty folder on another partition that has been formatted with the NTFS file system. Mounted drives are typically assigned a label or name instead of a drive letter. They're useful for organizations that need to share partitions or drives with many users. A mounted drive is also known as a mounted folder.

Mounted drives let you extend the storage capacity of a drive or partition. Say you save financial records to the Finance folder on drive C, but drive C is getting full. A separate drive, drive E, has room. By creating an empty folder in the Finance folder called Records, and mounting drive E to the new folder, you can then save files to C:\Finance\Records to take advantage of the extra storage space on drive E. Mounted drives have an advantage over shortcuts because you can move the mounted drives without having to update the folder that the drive is mounted to.

Notes

  • The Recycle Bin doesn't recognize mounted drives, so if you try to delete a file that's stored in a mounted drive, you might receive an error. To bypass the Recycle Bin and permanently delete the file, click the file, and then press Shift+Delete. When you permanently delete a file, you can't recover it unless you have a current backup copy of the file.

    You can't mount an ISO file using Windows, but there are third-party programs available with this capability. To access an ISO file, you must first burn it to a CD or DVD. For more information, see Burn a CD or DVD from an ISO file.
