The move function does work fine locally just not when trying to move across the CQ server.
Bridge is designed for single user purposes and officially does not support use over a network. Not said it does not function in a network environment, it is just difficult to set up and to maintain.
Using Bridge to move a file should move it to that location instead of copy unless the folder is on an other disk which logically creates a duplicate on the new disk.
Also try the dedicated CQ5 forum:
