You can choose whether to include a download link for your judges with entry attachments. This will allow judges to easily download the original file upload from a given entry to their computer.
In the Manage workspace, go to Judging > Settings > Score sets
Click the name of the score set you want to edit
Open the 'Display' tab
Select or deselect the checkbox next to Allow attachment download
Save
Note: disabling attachment download for judges will remove the download option in both attachment-type tabs as well as for file upload (single) fields. Doing so will also disable the ability for judges to zoom into PDF attachments.
