Folder → tag
Drop a file into a folder, and matching tags appear in frontmatter. Transform naming conventions on the way (Title Case → snake_case, strip emojis, handle Johnny Decimal prefixes).
Folder Tag Sync
Bridge Obsidian's rigid folders and flexible tags. Deterministic, rule-based, no AI inference.
The core idea
Section titled “The core idea”A file lives in exactly one folder. But knowledge rarely fits one category — a Q4 retrospective is a project, an archive, a meeting, and something Alice worked on, all at once. Tags let you say so. Folder Tag Sync keeps both views in lockstep.
Why this plugin
Section titled “Why this plugin”Folders are rigid, single-hierarchy structures required for file storage. Tags are flexible, overlapping hierarchies better for knowledge representation. You need both — and you need them to stay in sync without having to think about it.
Folder Tag Sync bridges the two with deterministic, rule-based transformations. No AI inference. No surprises.
Tag → folder
Add a tag to a note, and the file moves to the right folder. Reverse the naming transformations cleanly.
Regex-powered
Match paths and tags with regex. Named capture groups. Multiple rules with priority ordering.
Transformation pipeline
Compose case conversions, emoji handling, number-prefix stripping, and custom regex into per-rule pipelines.
How it works
Section titled “How it works”File event → Rule matcher → Transformation pipeline → Sync executor- Rule matcher finds rules by priority using regex patterns
- Transformation pipeline converts between folder and tag naming conventions
- Sync executors update frontmatter tags or move files
Current status
Section titled “Current status”Phase 1 complete: core transformations, rule matching, both sync directions, settings UI, 156+ automated tests.
