Obsidian

Obsidian vault = a normal folder on disk.

Vault structure (typical)

• Notes: *.md (plain text Markdown; edit with any editor)
• Config: .obsidian/ (workspace + plugin settings; usually don’t touch from scripts)
• Canvases: *.canvas (JSON)
• Attachments: whatever folder you chose in Obsidian settings (images/PDFs/etc.)

Find the active vault(s)

Obsidian desktop tracks vaults here (source of truth):

• ~/Library/Application Support/obsidian/obsidian.json

obsidian-cli resolves vaults from that file; vault name is typically the folder name (path suffix).

Fast “what vault is active / where are the notes?”

• If you’ve already set a default: obsidian-cli print-default --path-only
