Files with no extension - Microsoft Community
answers.microsoft.com › en-us › windowsDec 29, 2021 · I have several files with no extension. Under file type, it just says "file". I'm not sure what happened tom change that. I recently downloaded Windows 11, if that means anything. My question is, is there any way I can add an extension to a file that would make it readable? Any help would be greatly appreciated. Thanks. bigbeardedbuddy
