How to get Windows to ALWAYS open up folders in XYPlorer

[prr]

I have already made XYplorer my default, per https://www.xyplorer.com/faq-topic.php?id=dfm.

However, when I use Copernic desktop search, and click on a file in the results, it never uses XYplorer. Is there something else I need to be doing? I did a search, and found this page linked to, viewtopic.php?p=214531#p214531, but I'm not sure how it would make the search results appear in Explorer. Does someone know enough coding to made a tweak of one of those registry bits?

Also, before I make those registry keys and insert them into the registry, do these over-write anything, or do they merely create new keys?

Then try it out if it works?

[HKEY_CURRENT_USER\Software\Classes\CLSID\{20D04FE0-3AEA-1069-A2D8-08002B30309D}\shell]
@="*Q-Dir"

These type of entries overwrite the default value so make sure to look them up via regedit before doing that.
The others create additional keys

OK thanks, I'll search through regedit to see if they are already existing. Making a backup of the registry probably wouldn't be a bad idea, either.
