Thanks again However I believe that you misunderstood me, I don't know how to use BSABrowser (I can't even launch the thing) NOT TESRename. I do know how to use TESRename from the tutorial that came with the zip file I downloaded (the same that you posted) and it works great !!! So I do not really need BSABrowser but I am curious to see how it works. Thanks again though since I did not know about TESRename !
