How to open any file

231 step-by-step guides, one per format, with the exact free apps that open it on Windows, Mac and Linux.

Pick the extension you are stuck on. Each guide names real apps per operating system, flags whether the file is safe to open, and links out to that format's full details and, where useful, a converter.
