Explains how you can regroup your archives.
Moving an archive to another group
When you create an archive, you can also define the group that it belongs to on the archive properties page. To change the group that the archive is part of, you can open the archive's properties by right-clicking it and choosing Properties. However, you can also select the archive in the main program window and drag it to another group, then drop it on the group header of the new group. Group headers must be turned on in the side panel’s properties page for this to work.
