Reply To: Need help to clean my collections please !

Thank you for the answer, unfortunately that is not working. The problem seems to be that all the objects are in another object. When i try to move something, that just makes a copy and if i try to unlink it delete all the copies. Also tried to move in a new collection and delete hierarchy, every time it is the same result, i can not delete one copy without deleting every other copies. If i delete the floor, i delete everything :p
