The Merge function becomes available in the Edit Virtual Hard Disk Wizard specifically when working with a differencing disk. A differencing disk, which is created when a virtual hard disk (VHD) is used as a parent to one or more child disks, keeps track of changes made to the parent disk while the parent remains unchanged. This allows users to create multiple snapshots or versions based on the same parent disk.

When the Merge function is invoked for a differencing disk, it consolidates the changes recorded in the differencing disk back into the parent disk. This is a crucial operation when you want to finalize changes made in a virtual environment, ensuring that the parent disk reflects all modifications made by the child disks.

Utilizing the Merge function creatively supports effective management of storage and snapshots in virtualization, especially in scenarios involving backups or versioning. The availability of the function in this context underscores its role in efficiently handling the virtualization lifecycle, enabling administrators to maintain organized and optimized virtual disk storage.
