Download multiple documents in the same link

You could use one of the available plugins and encapsulate all of the documents you want to download as a zip file, so now it'd be a single document object that you could download with the link. Otherwise, no, one link downloads one document. 

Hi,

This might not be the best solutions, but if it meets your requirement you can try. Show or select (In side grid) all the documents that you want to download then provide a link for user to merge all the selected documents. Once documents are merged in a single file you show a link to download or show a preview document they can downloads from there.
