winget install --id=GnuWin32.File -eDescription
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.
File is available through winget as package ID GnuWin32.File, with version 5.03. Use the install command above to set it up on Windows without downloading a separate installer manually.
