If you operate an exchange or a similar temporary folder, this plugin does the cleanup job for you. For each defined node you can specify a maximum age for assets within, after which they will be deleted automatically (based on the upload date).
You can configure if the asset should also be deleted if it's linked to other nodes as well and if empty nodes should be deleted too.
