I've tried numerous file download components but still have yet to find one that works for me. Although I must say JotLoader is very good, if only it can do a bit more. I have a several thousands files stored in a directory structure where from the top directory, multiple sub-directories and layers exists. JotLoader is great, but only able to detect file in one single directory with no recursive look up for the directories beneath it. I've also attempted to set the "download" dir to the top level folder and then manually add files. However, the module doesn't seem to be able to add files that already exists in the server. Nevertheless, Jotloader is worth looking into for anyone without my complex structure.
