Hello,
PowerToys New+ / NewPlus works well explorer.exe:
But PowerToys New+ / NewPlus won’t create item in Directory Opus 13.12 (x64):
Related issue: New+ does not work in Directory Opus alternative file manager · Issue #35192 · microsoft/PowerToys
There's a thread here about how to do the same thing (and more) using Opus's built-in functionality: How to create new buttons? (Don't worry about the generic thread name, it is about New+.)
