Magic File Renamer (MFR) is a batch file renamer and audio tagger for Windows. With MFR you can change names, dates, and attributes for files and folders, and update tags for many popular audio formats.
Build a Filter Chain of reusable filters for batch renaming—so you spend less time renaming by hand. The Formatter filter builds names from patterns and can pull data from audio tags, media properties, image/EXIF data, and document Info (PDF, EPUB, Office).
The UI stays approachable while staying flexible for power users. Real-time preview for any field, presets, logging, undo of the last operation, and a command-line console for automated processing are part of that toolkit. MFR handles large batches and stays responsive.
Whether you organize music, photos, or large folder trees, MFR fits the same workflow: build a chain, preview, then GO.
This version (Magic File Renamer 8) is a rewrite of the classic MFR 7 desktop app. See What's New, Migrating from MFR 7, the Feature List, and Supported Formats for what ships today.
