Abstract: The embodiments relate to transcoding, cataloging, and extracting metadata about files stored in a storage device. In one embodiment, a crawler runs on the storage device and maintains a database that is stored in the volume with the data that has been cataloged by the crawler. The crawler may discover files of any type and extract associated metadata about the files. The crawler can extract metadata about client interaction with various files, such as edits, play counts, etc. The crawler may discover files of any type and extract associated metadata about the files automatically during a scan or at the request of a client. In one embodiment, the crawler may be responsive to file system events that indicate changes to the file system, such as additions, deletions, or other types of changes. In addition, the crawler may synchronize the database with the file system so that they indicated the same state for a particular file. Furthermore, the crawler may provide notifications to various entities regarding the state of a file.
