When We Add Resource To Our Project It Is Converted To "uasset"?

Hi Again,

We noticed just now that if we right-click on the resource in the UE4 editor
we can select option: “Open In External Editor”.

The only issue with the above is that it opens the PNG image in MS Paint application?
Is there somewhere where we can change the default PNG image editor in UE4?
(Our Windows 10 OS already has the correct PNG image editor selected)

Let us know, thanks!
