Aspects of the subject technology relate to archiving user generated content. A data storage device of a computer system is scanned for media files, and directories of the data storage device containing media files found during the scan are added to an upload directory list. For each directory in the upload directory list, respective identifiers for the media files contained in the directory are determined and sent to a server. Confirmation is received from the server of whether the sent identifiers match identifiers for media files already stored by the server. The media files having identifiers confirmed as not matching identifiers for media files already stored by the server are uploaded.
