Overview

Magic File Renamer (MFR) is a batch renamer and audio tagger for Windows. Rename files and folders, adjust dates and attributes, and update tags across common audio formats — all in one place.

Build a Filter Chain from a large set of filters to handle nearly any renaming job without tedious hand edits. Pattern renaming with the Formatter pulls values from audio tags, media properties, image/EXIF data, and document Info (PDF, EPUB, Office).

Preview every field before you apply, save presets, keep a rename log, undo the last operation, and automate with the mfrc console. MFR is built for large batches and tuned for speed, without burying the essentials behind complexity.

Whether you organize music libraries, photo shoots, media archives, or everyday collections, MFR fits the same workflow: build a chain, preview, then GO.

Magic File Renamer 8 is a full rewrite of classic MFR 7. See What's New and Features for what's included.
