A device receives, from a content provider device, a personal media file with a custom name and generates a universal file name for the file based on a digital fingerprint extracted from the file. The device associates the universal file name with the custom name and determines that the universal file name is associated with a previously-stored file, where the previously-stored file and the file with the custom name have an identical digital fingerprint. The device discards the file with the custom name, and associates the custom name with the universal file name for later retrieval. |
