The mere ability to double click the file so it opens in some editor doesn't causing any problems.
(I have all kinds of files linked to editors for years).
Much more important would be to know if your Windows is set to hide known extensions or not.
Right-click on that file and see if it isn't named Resource.cfg.txt by any chance.
