The program features a simple and quite user-friendly interface where you can view the filepath and complete list of files to be renamed.
Additionally, from the main window you can access all tag-altering commands so you can see the direct results of your changes. From the application you can also modify the extension of certain files, replace duplicate files, or run queries faster than using Windows' explorer.
For MP3 files, Rename Master supports ID3 tags, from which you can modify the title, artist, year, or album. The program also lets you change image tags for JPEG, JFIF, and EXIF files.
