I’m wondering if you would like to consider the following feature, which I personally think would significantly add value to users desiring to do multiple downloads of heavy files (e.g. video files): why not display an additional column (e.g. as the first column), allowing the user to put tick marks on those elements he or she would like to download. You might also want to display a button labeled say “group download”. Once the user clicks on group download (and provided he or she has already selected files) the normal window appears allowing him or her to specify the destination directory and potentially the name of the package to be downloaded. The result would be the download of a zipped package of the selected files.
What do you think?
