MFR vs ReNamer (den4b)
ReNamer by den4b is an ordered-rule Windows renamer with rich meta tags and Pascal Script. Magic File Renamer is the closest peer when you want a Filter Chain with Apply To, presets, Formatter tokens (including PDF/EPUB/Office Info), ID3v2 Field Setter depth, and Path Mover — without relying on scripting (use Generate Rename Script or mfrc instead). Among these tools, only MFR writes audio tags (MP3, FLAC/Ogg/Opus, M4A, WMA, WAV, APE, and more) and live-previews tag columns — not names alone — before Apply. Filter Chain steps also use Apply To on writable fields (names, extensions, tags, dates, attributes), not filename-only rules.

Choose ReNamer if…
- You need Pascal Script for custom rename logic.
- You already prefer den4b’s rule + meta-tag naming workflow (rename, not retag).
Choose Magic File Renamer if…
- You rename and retag with Apply, Apply To, ID3v2 Field Setter, and live tag-column preview.
- You want Path Mover folder trees and document Info tokens without Pascal Script.
- You prefer Filter Chain presets plus mfrc, Generate Rename Script, and Explorer right-click rename.
FAQ
- Is Magic File Renamer a den4b ReNamer alternative?
- Yes for Windows users who want ordered filters with built-in audio tag write / Apply (and tag-column preview), Apply To on tag fields, ID3v2 Field Setter, and Path Mover. ReNamer remains the better fit when you need Pascal Script for custom rename logic.
- How do Filter Chains compare to ReNamer rules?
- Both are ordered stacks you can save as presets. MFR emphasizes casing/spacing/trimming filters with Apply To on names and tags, plus Formatter tokens and audio Apply with tag preview; ReNamer emphasizes flexible rules plus Pascal Script for edge cases. For non-Pascal automation, MFR offers Generate Rename Script and mfrc.
- Does ReNamer write ID3 tags?
- den4b documents ReNamer as a renamer that can read meta for naming — not a tag editor — and states that editing meta tags is not a feature they intend to add. Choose Magic File Renamer when you need audio tag write / Apply (MP3, FLAC/Ogg/Opus, M4A, WMA, WAV, APE, and more) with tag-column preview and ID3v2 Field Setter; keep ReNamer when Pascal Script and rule-based rename are enough.
