Help & FAQ/Import guides
An Obsidian vault is already a folder of Markdown files, which makes this the easiest migration of all: zip the vault, drop it in.
YAML frontmatter is understood: tags, aliases, and created dates are honored. Subfolder paths become tags (a note in Work/Projects picks up "work" and "projects"), and inline #tags in the body are merged into the tag field.
Your [[...]] links keep working: PrivacyNotes renders them as note-links, so the connections between notes survive the move. The .obsidian config folder and .trash are skipped automatically.
