Find out what kind of file something really is
A file name can be wrong or missing its ending. Choose the file and the tool tells you what it really is, so you know which program or tool can open it.
It helps when a download has no extension or a document will not open. If the result matches a format we support, open it with the right tool here.

Questions
Is the file opened or run?
No. Only its contents are read; nothing is opened or started.
How many file types does it know?
About 50 common types: documents, images, audio and video, archives and programs.
Why would a file have the wrong extension?
Files get renamed or downloaded without an ending, so the name no longer matches the content.
Is the file uploaded?
No. It is checked on your device.
