Abstract
Systems and methods are disclosed for reconstructing a file hierarchy by scanning attributes of stored files. Stored files can have a file hierarchy that is maintained in a database stored on a storage device. The files can be stored as objects on the device using a flat file structure. The file database provides the file hierarchy. The systems and methods disclosed herein store information in file system extended attributes for individual storage files such that the database can be reconstructed by scanning the storage files, using values in the extended attributes to recreate the hierarchical database.
