Filemover removed, I just removed your file mover user right because I found that is was not used in line with to our policy on file renaming, Commons:File renaming. If I misunderstood something, feel free to contact me. Otherwise you may request this right again at Commons:Requests for rights explaining how you will use it in future.
File renaming is problematic because it breaks links, image inclusions on external websites and even temporarily on the Wikimedia Server cluster. It also adds a lot of workload to the servers because its technical implementation is sub-optimal. That's why we have such a strict policy.
Besides the technical issues, lots of different people have different options about how a file should be named.
