When the folder is empty, the link to "Download as zip file" should not show

[Son Nguyen]

Version: master

The link to "Download folder content as a zip file" should not show if the folder is empty

[Robert Lyon (robertl-9)]

This would all depend on whether all subfolders below this folder are also empty as well

The logic to control the print of the link was all implemented on the view layer. As the link to the parent folder is listed as another row on the files list, the conditions for printing the link are: -there are two or more rows on the list OR -theres only one row on the list, but it is not a link to the parent folder.
With this solution subfolders are considered a content even if they are empty, so the case of downloading the zip of a folder full of subfolders but all of them empty is still posible.
