Download! includes a download and purchase history feature. This feature enables you to keep track of downloads and purchases made. It is used, for example, to indicate items that you have already purchased. To open the download and purchase history, select Options > My items > Purchase history.
When you select this option, a list shows you all the items that have been purchased. From the list you can also launch or view content, or directly browse to content in the catalogue, if it is still present in the cache. Subscribed content is not shown in the purchase history, as it is managed through the Subscriptions view.
The purchase history is maintained, even if you empty the client cache.
