UI freezes when moving folder with drag & drop (on Windows)

[EmadFathy]

When trying to move a folder with drag & drop, the UI of the app is freezing a lot of time (and sometime go black), for the test captured in the following video the two folders was empty and it froze about a minute. I made a video to show the problem.
