A lot of disk space may be consumed after upgrading to 6.5

Behavior:
In DocuWare 6.5 the Web Basket recycle bin has been removed. However, the recycle bin is not cleared during the upgrade from the previous release and therefore orphaned recycled documents remain on the system.
This behavior has been reported to DocuWare Product Development.

Solution:
Before you perform an upgrade to DocuWare version 6.5, it is highly recommended to empty web baskets recycle bin.
