Don't know what program to use to open an unknown file?
The File Extensions application helps you quickly identify unknown file types based on their extension.
Main features:
A database of over three thousand file types – find out what .docx, .mp4, .iso, .apk, .db or even rarer formats mean.
Search by extension – enter, for example: pdf, and you will immediately get a detailed description.
Search for words in the description – if you don't know the exact extension, a keyword is enough (e.g. "image", "music", "database").
Fast and offline use – the basic database is available even without an internet connection.
What is it good for?
- If you have downloaded an unknown file and don't know how to open it.
- If you often encounter different file types as a system administrator, IT specialist or developer.
- If you are simply curious about what strange extensions mean.
A simple, fast and useful utility for all users who want to organize their files.
