File is a Free Windows program in the Other category, developed by GnuWin32. The current version is 5.03; you can download it safely from its official source with the download button above.
The file command is "a file type guesser", that is, a command-line tool that tells you in words what kind of data a file contains. Unlike most GUI systems, command-line UNIX systems - with this program leading the charge - don't rely on filename extentions to tell you the type of a file, but look at the file's actual contents. This is, of course, more reliable, but requires a bit of I/O.
