Problem

Take for instance: Why doesn't this file have an extension such as , , etc? Or does an extension exist, but it's just being hidden? Does this apply strictly to Unix-like systems?

Fix for: How does a file have no extension?

Low Risk

There is no extension. There's no reason for one. This isn't unique to Unix. You don't have to have a file extension in Unix or Windows. Windows won't know what to do with the file if you double-click it, but the program that made it probably does.
