IEmptyVolumeCache interface (emptyvc.h)
Used by the disk cleanup manager to communicate with a disk cleanup handler. Exposes methods that enable the manager to request information from a handler, and notify it of events such as the start of a scan or purge.
The IEmptyVolumeCache interface inherits from the IUnknown interface. IEmptyVolumeCache also has these types of members:
The IEmptyVolumeCache interface has these methods.
Notifies the handler that the disk cleanup manager is shutting down.
Requests the amount of disk space that the disk cleanup handler can free.
Initializes the disk cleanup handler, based on the information stored under the specified registry key.
Notifies the handler to start deleting its unneeded files.
Notifies the handler to display its UI.
This interface must be implemented by disk cleanup handlers running on Windows 98. Handlers running on Windows 2000 should also expose IEmptyVolumeCache2.
