Quad-Dir-Explorer work on 64-bit, but it is a 32-bit application, Just install under Win-10 64 7zip 32bit, there is no difference in performance.
Then it also works in Q-Dir.
But in future I will make Q-Dir also as a 64-bit application!
From version 3.73 : Please download the x64 Q-Dir files for x64 OS:
Please always use .... the newest and latest version of File Explorer Q-Dir!
