Remarks

A disk cleanup handler uses this interface to report to the disk cleanup manager on the progress either of deleting files or of scanning for deletable files. It also provides a way to query the manager, to find out if the user has canceled the operation. The handler receives a pointer to this interface when the manager calls the IEmptyVolumeCache::GetSpaceUsed or IEmptyVolumeCache::Purge methods.
