Can quick file renamer work without having to copy the files? Can it simply rename a directory in place?

I'm sure I'm doing something wrong. I'm transferring a large number of files from my old computer to my new. As I go through the old files and copy the directories to my new computer, I want to rename the old directories with the prefix "DONE".

I configured the renaming action, and it is running, but it seems to copying each directory with the prefix, rather than simply renaming the directory in place! I don't need new copies of the directories -- it's taking too long, and filling up my backup drive. What did I do wrong?
