Revert .package files help!!!!

Ok so I accidentally turned all my package files to word files just like the original commenter mentioned. But they are all registered as package files, so should they work for my game? I'm a little afraid to go on it, and I just want a little simple yes and no answer because it's a little hard to read what you guys are saying.

(As you can probably tell I'm not a very, "techy," person, sorry if my reply seems ignorant)
