Source facts

\n

Microsoft describes a folder mount point as a way to access a drive through a folder path. The operation can be performed with Disk Management, command-line tools, or PowerShell. Its prerequisites include an empty destination folder on an NTFS or ReFS volume. The folder may reside on a basic or dynamic disk. Microsoft also specifies administrator permissions for opening the relevant management tools with elevation. Microsoft documentation.

\n

Applicability

\n

Identify the volume to mount, the containing volume, and the exact empty folder. Review the application paths that will use the mount point and the administrative account authorized to make the change.

\n

DSE recommendation

\n

Have another administrator compare the proposed volume identity with the intended folder path. Record the existing access paths and obtain application-owner agreement on the new path. Establish how the mount point will be removed or recreated if testing exposes an unexpected dependency.

\n

Verification

\n

After an approved test, access a known file through the new folder and verify that it belongs to the intended volume. Check access using the relevant application identity, then review monitoring and backup coverage for the resulting path. Preserve the before-and-after volume mapping and any access failures in the change record.
