Space Utilization By File Type
The Space Utilization by File Type chart displays space used by virtual disks, swap les, snapshot les, and
other virtual machine les on the datastore or the datastore cluster.
N This chart does not show historical statistics. It only shows the most recently available data, which
may be up to 30 minutes late, depending on when the last statistics rollup occurred. In addition, statistics
are not collected across all datastores at one time. They are collected asynchronously.
The Space Utilization by File Type chart is located in the Storage view of the datastore Performance tab. The
counters can also be displayed for datastore cluster charts.
Datastore Counters
Table 1‑27. Data Counters
File Type Description
Virtual Disks Amount of disk space used by virtual disk les.
Virtual disk les store the contents of the virtual machine's hard disk drive. It includes
information that you write to a virtual machine's hard disk, such as the operating system, program
les, and data les. The les have the extension .vmdk and appear as a physical disk drive to a
guest operating system.
N Delta disks, which also have an extension .vmdk, are not included in this le type.

Snapshots Amount of disk space used by virtual machine snapshot les.
Snapshot les store information about virtual machine snapshots. They include snapshot state les
and delta disk les. A snapshot state le stores the running state of the virtual machine at the time
of the snapshot. It has the extension .vmsn. A delta disk le stores the updates made by the virtual
machine to the virtual disks after a snapshot is taken.
