I have exactly the same experience....
the graphical starts to spin and u can wait for hours... only 1 folder is being made but empty..
it doesnt work anymore since the update of the file manager.
I just found out... when i choose MOVE instead of COPY... it works half. the source folder is empty and the target folder looks like to be filled up... but isnt. folders are moved but the content inside the folders, half of is missing or miss placed in the wrong folders.
