What can be inferred about a datastore with a snapshot file named "Win10-000001-sesparse.vmdk"?

The presence of a snapshot file named "Win10-000001-sesparse.vmdk" indicates that the datastore is formatted as VMFS6. This format introduced a new type of sparse virtual disk file that allows for more efficient storage of space used by snapshots.

In VMFS6, the "sesparse" type is a feature that optimizes space for virtual disks that have been snapshot. This means that when a snapshot is created, the file uses less physical space on the datastore by tracking only the changes made, rather than duplicating the entire virtual disk file. As a result, having a snapshot file with the "sesparse" designation is a clear indicator that the underlying file system is VMFS6, as this feature is not available in VMFS3 or other previous versions.

Choices related to raw device mappings or vSAN datastores do not provide the context for the specific file naming convention related to VMFS. Therefore, the identification of the file type clearly supports that the datastore is indeed formatted as VMFS6.
