Comments
For storage objects opened in transacted mode, the IStorage::Revert method discards any uncommitted changes to this storage object or changes
that have been committed to this storage object from nested elements.
After this method finishes, any existing elements that were opened from the
reverted storage object are invalid and can no longer be used. The error
STG_E_REVERTED is returned on all calls except IStorage::Release using these openings.
For storage objects opened in direct mode, this method has no effect.
