PowerRenamer

PowerRenamer can change names of selected items in Finder with searching and replacing strings. You can choose a searching condition from some patterns and the regular expression. Also you can add sequential numbers into filenames.

PowerRenamer is simple but enough powerful. The design is focused on intuitive and quick operation. On the other hand, PowerRenamer can preview the renaming result before actual renaming, if you want.

PowerRenamer was selected as Mac Informer's "Editor's Pick Award"
