Help: Files won't open with program they opened with yesterday...

I made some .RPP music files with a DAW called Reaper. Yesterday reaper.exe was in a folder something like:

C:\Program Files\Common Files\VST3\VSTs etc

and I highlit one of the files, chose Open With, did the Browse, selected reaper.exe, and it opened fine as did all other .RPPs and I thought things were going well. But today I moved the VSTs etc folder to just C:\VSTs etc and then the .RPPs wouldn't open with Reaper any more. So again I highlit, browsed, chose reaper.exe, but from there instead of opening and things going well nothing happened. After trying it MANY times it still never worked. Can anyone help me understand how to make it work again like it did the day before?

Thank you for any help!

Well another question then...I've seen a place in Windows that lists all the types of files and what they open with and you can make changes there, but can't remember what it's called or how to get to it. Maybe that could help. Can anyone tell me about that?

Thank you! That eventually led to the same path as the Open With route though, and with the same (lack of) result. I never did learn what the problem was, but deleted the program and reloaded it, and then it worked like it was supposed to.

That works too
