How to Clear or reset the "Open With" list

Yes sir! That was the fix. I should have thought of that but was convinced this was way out of normal. Seems like this might be a nuisance, though, if it continues. I only had(have) one copy of those apps and are in Applications. No sub folders of apps either. Thanks so much for the assist! Wonder why Onyx didn't do it. Am using the most current version of 4.4.0. Oh well!

Well....the list was normal all day after booting into safe boot yesterday. But then this morning it came back to the long list as shown above when I logged in before doing anything else. Any other ideas? Is anyone else seeing this anomaly?

I have not yet tried the example from Terminal I posted but I will when (if) it happens again. Oddly, I just performed a normal reboot (Not using Safe Boot) and the long list disappeared and was normal again. Also, for the record, I do not use any 3rd party optimizers or anti-virus apps. Only MalwareBytes.

I did and thought it had fixed it but the problem returned. Also, after I reboot, the list is short as expected but in a few minutes, the list comes back to the long duplicated list. I will try logging in as a new admin user and also in safe mode to see if the problem comes back which will at least determine if it's isolated to my default user account or not. This is just an annoying problem but not a serious problem. I guess!

Well, the problem came back again. So I ran the script and rebooted. Unfortunately for me, the problem did not go away. Back to the drawing board I go.
