Currently AWB does not seem to be able to move/rename files on Commons. It would be good if AWB could be modified to allow people to rename files.
We already have a tool. It can not be in the autowikibrowser because it must be renamed globally, and the autowikibrowser does not support it, Ie. contributing to multiple projects at once. For each project needs to open a new window of autowikibrowser. We have GlobalReplace tool for find and replace files globally across Wikimedia Projects.
