you used to have this in your freeware version. A way to find out if a file has been encoded with the wrong entension so if a rar extention should be a zip for example. it can happen. I've had that problem cause of a virus. well worth having this feature.

I agree this would be a good idea, some people rename there files and accidently remove the extension and then forget what is was, and put the wrong extension.
