FILExt: Free File Extension Database

Discover unknown file types, get associated programs and information on thousands of file formats with FILExt, a free online database

What is FILExt?

FILExt is a free online database that provides detailed information on various computer file extensions and their associated programs. It contains a comprehensive directory of over 5,000 file extensions and file formats.

The key feature of FILExt is its ability to help identify unknown file types. Users can search by file extension and retrieve a description of the file type, what program opens it, what it's used for, and other useful details. This makes it easy to figure out mysterious file extensions spotted on your computer.

Beyond file identification, FILExt provides additional details on common file types. For example, for .DOCX files it explains that it's a Microsoft Word Open XML Document format introduced in Word 2007. It provides a brief history, notes Microsoft's ownership, and related information.

There are convenient outdated and fallback lists showing relationships between old and new file formats. Searches can also be conducted by file format name directly.

FILExt includes a tracking feature to monitor the latest updates and new entries added to the database on a daily basis. The vast database and helpful search functions make FILExt a practical tool for anyone dealing with many file types.
