If it’s in any of the FILExt databases the data we have on that file extension will be shown on a results page. If it’s not in any of the databases you will be given a link to a page with hints on how to do further research. Don’t search on terms; just file extensions and only one at a time please. There will be another search box on the results page if you have multiple searches to do.
