When MSS files are removed or are purged, they are placed into a special area of the MSS called the trash. The name of the MSS file is prefixed with /trash. While in the trash, the only metadata operations that can be performed are msls and msrecover. MSS files may not be read or written while they are in the trash. While MSS files are in the trash, but before they have been permanently deleted, they can be restored with the msrecover command.
