📝 File Templating

Templates are text strings that describe folder and file structure. They use placeholders (in {curly_braces}) that get replaced with actual metadata values from:

• Track / Video → item
• Album → album
• Playlist → playlist
• Plus any custom fields

A template like:

{album.artist}/{album.title}/{item.title}

becomes this:

Daft Punk/Discovery/Harder Better Faster Stronger

extra and custom fields

🧼 Sanitization

All template segments are sanitized:

• Invalid filesystem characters are removed or replaced.
• Empty placeholders are skipped cleanly.
• Each path component is treated separately (split by /).

---

⚙️ Configuration Example

Your [templates] section in config.toml defines templates per media type.

[templates]
default = "{album.artist}/{album.title}/{item.title}"
track = "tracks/{item.id}"
video = "videos/{item.title}"
album = "artists/{album.artist}/{album.title}/{item.title}"
playlist = "{playlist.title}/{playlist.index}. {item.artist} - {item.title}"
mix = "mixes/{mix_id}/{item.artist} - {item.title}"

If no specific template is set, the default one is used.

🧠 Tips

• You can format datetime fields, e.g. {album.date:%Y-%m-%d}.
• You can build nested folders safely using / separators.
