[Issue] with Folders

4.16.2
if me deleting folders, after me click delete (delete folder ‘blah’ delete cancel dialog) the engine hang
and after a long time waiting and surfing in web there is no pop up window where usually the delete confirm is.

if me moving a set of folders into a new one also result often in hangs.

at least please make a progress info what the engine do for the long time so that i can tell you why i am waiting.

it will be much better if this task run separate from editor.
