File-ID.org is a free, open-access file archive maintained by Social Psychology Network, a nonprofit educational organization established in 1996. The archive currently contains more than 22000 files, including images, slide presentations, text files, and data files. Most files relate to the social and behavioral sciences.
Anyone with a Social Psychology Network profile can archive files by opening the Files tab when editing their profile and clicking on the Upload button. For details, please see this video tutorial. At present the archive is not searchable; instead, archived files are accessible under the Files tab of SPN profiles.
