We continuously evolve our external sharing solution Sharebox for Alfresco. Some of the latest added features are the ability to exclude files and folders from the sharing, filters in the document library sidebar to quickly list Sharebox folders and the ability to customize external client header title to hold the organizational name.
We use Sharebox at Loftux, among other things, we use it to distribute Software and Sharebox itself. We prepared this short video that demonstrates how we do it in combination with the Symbolic Linking available in LXCommunity ECM.
