messed up .snt sounds! please help ...

The issue is that you've set a default program, like Flawless says, to the .snt extension.
In addition, you also have "Known extensions hidden", which is a setting in Windows Explorer. To enable extensions (which I recommend) click on the View tab, then check the box for "File name extensions".



Once that is done, to reset the default program, again, as Flawless says, right click one of them and choose "Open with > choose another app" which will give you a window where you can pick an app. If Notepad is not in the list, click "choose another app on this PC".



Ignore the .png extension in the image. Yours should say .snt.
If you have Notepad++, I recommend it instead.
