Advanced Renamer (formerly ARen) is a batch renaming utility, that makes it easier to rename any number of files or folders. It supports 7 different renaming methods and also supports MP3 tags. You can rename the files with an increasing number, add a prefix and extract information directly from the file attributes or ID3 tag to be included in the new name. Next to standard renaming, change the case, change attributes, replace strings in the file name and more. The program is easy to use and allows you to instantly preview the new file names, before processing your files.
