Search for Music to install

fnOS users can now find and install Music Organizer directly from App Center, without downloading an FPK first.

Still need a manual install?

FygoOS users, or fnOS users who cannot see the listing yet, can download the matching x86_64 or ARM64 FPK above and use Manual Install in App Center.

Local files only

Turn local audio files into an organized music library

Place NCM or common audio files on your NAS to get started. Music Organizer does not provide music resources or download services; it only processes files already stored on your NAS.

01

NCM conversion and plain-audio organization

Convert NCM locally; existing MP3, FLAC, OGG, M4A, WAV, AIFF, Opus, DSF, and AAC files are read for metadata and copied byte-for-byte without uploading or re-encoding your library.

02

Metadata-based organization

Organizes converted tracks by artist and album, with configurable archive layouts and predictable fallbacks for missing metadata.

03

Controlled batch tasks

Scan before starting, monitor file-level progress, pause after the current file, and retry failed files when needed.

04

Lyrics and artwork together

Carries matching lyric and cover sidecar files into the organized output when they are available.

Workflow

A clear three-step path

Every task stays explicit, from the folders it can access to the files it will create.

  1. 01

    Choose source and target folders

    Select folders already authorized in fnOS or FygoOS and choose the archive layout that fits your library.

  2. 02

    Scan and verify

    Review the supported file count, expected output size, available space, conflicts, and task concurrency before creation.

  3. 03

    Start and monitor

    Run the task when ready, follow progress from one screen, and inspect failed or skipped files without touching completed output.

Safety by design

Your source library remains the source of truth

Conversion is designed around conservative file handling, so a batch task cannot silently rewrite the collection you started with.

  • 01

    Source files are opened read-only and are never deleted or modified.

  • 02

    Existing target files are skipped and never overwritten.

  • 03

    Deleting a task removes its records and logs, not source or output files.
