Funkwhale can import music files that are located on the server assuming
they readable by the Funkwhale application. Your music files should contain at
least an ``artist``, ``album`` and ``title`` tags, but we recommend you tag
it extensively using a proper tool, such as Beets or Musicbrainz Picard.
You can import those tracks as follows, assuming they are located in
Funkwhale supports two different import modes:
- copy (the default): files are copied into Funkwhale's internal storage. This means importing a 1GB library will result in the same amount of space being used by Funkwhale.
- :ref:`in-place <in-place-import>` (when the ``--in-place`` is provided): files are referenced in Funkwhale's DB but not copied or touched in anyway. This is useful if you have a huge library, or one that is updated by an external tool such as Beets..

Thus, be especially careful when you manipulate the source files.

Metadata updates
^^^^^^^^^^^^^^^^
When doing an import with in ``in-place`` mode, the importer will also check and update existing entries
found in the database. For instance, if a file was imported, the ID3 Title tag was updated, and you rerun a scan,
Funkwhale will pick up the new title. The following fields can be updated this way:
- Track mbid
- Track title
- Track position and disc number
- Track license and copyright
- Album cover
- Album title
- Album mbid
- Album release date
- Artist name
- Artist mbid
- Album artist name
- Album artist mbid
React to filesystem events with ``--watch``
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
If you have a really big library or one that is updated quite often, running the ``import_files`` command by hand
may not be practical. To help with this use case, the ``import_files`` command supports a ``--watch`` flag that will observes filesystem events
instead of performing a full import.
File creation, move, update and removal are handled when ``--watch`` is provided:
- Files created in the watched directory are imported immediatly
- If using ``in-place`` mode, files updates trigger a metadata update on the corresponding entries
- If using ``in-place`` mode, files that are moved and known by Funkwhale will see their path updated in Funkwhale's DB
- If using ``in-place`` mode, files that are removed and known by Funkwhale will be removed from Funkwhale's DB
Pruning dangling metadata with ``--prune``
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Funkwhale is, by design, conservative with music metadata in its database. If you remove a file from Funkwhale's DB,
the corresponding artist, album and track object won't be deleted by default.
If you want to prune dangling metadata from the database once the ``import_files`` command is over, simply add the ``--prune`` flag.
This also works in with ``--watch``.
