# Organise and delete versions
Source: https://docs.aden.space/docs/help/your-music/versions/manage-versions

Tag versions, mark the final one, open and close them, and delete the ones you no longer need.
From the second version on, versions stack on a timeline. Each entry says when it landed and, on shared tracks, who uploaded it.

## Mark the final version [#mark-the-final-version]

Open a version's **…** menu and promote it. The promoted version carries a **Latest** or **Final** label, and it's what plays and shows everywhere the track appears: the board, the player, share pages.

## Tag versions [#tag-versions]

Click a version's tags to add or remove them, or type a new one. An untagged version shows **+ Tag**. You can also type "Tag" in ⌘K. Tags help search: "instrumental" finds the track it belongs to.

## Open and close versions [#open-and-close-versions]

Click a version's dot on the timeline, its entry, or the chevron on its card. Cmd or Ctrl click a dot to open that version alone and close the rest. Aden remembers which versions you left open, on every device.

* Click the timeline to hide or show the date column. Press, hold and drag it sideways to resize it.
* Drag the bottom edge of a version's tabs to make every card taller or shorter. Double-click the edge to reset.

Search sits above the list. Sort and **Compare** join it from the second version on.

## Delete versions [#delete-versions]

To delete one, open its **…** menu and delete it. It leaves the list as soon as you confirm, and comes back with the reason if the delete fails.

To delete several:

1. Hold ⌘ (Ctrl on Windows) and click the dots on the timeline.
2. In the bar at the bottom, pick **Delete**. The same bar offers **Share** and **Compare**.
3. Press Undo in the message if you change your mind.

People without delete access see the button greyed out, with the reason.
