Some examples describe a method for using location addressed storage as content addressed storage (CAS). A checksum of a file may be generated during transition of the file to a retained state. The generated checksum, which may represent a content address of the file, may be stored in a database. The database may be queried with the content address of the file to retrieve a location address of the file corresponding to the content address of the file. The location address of the file is used to provide access to the file in the file system.
