What Is a File Extension Searcher?

File extension searchers search file extension databases for information on file extensions, or file types, which is useful for troubleshooting purposes. Three popular file extension searchers that are usable online for free are FileInfo, File-Extensions and FILExt.

FileInfo

• FileInfo features file extension searches via both file type and alphabetical browsing. This website also allows web developers to add file extension search boxes to other websites.

File-Extensions

• File-Extensions allows users to search for file extensions directly using web browser search panels. This site also hosts overviews of both common and unknown file types.

FILExt

• FILExt provides instructions on how to conduct more research if users still can't find file types after searching their file extension database. Users can also access this website to search for file extensions from mobile devices.
