I like that you have an option to download all or part, depending upon how much storage space was available at my time when downloading.
In addition, they do offer several options as far as their pricing plan goes (including free). The only issue we ran into while using this software application in our organization's setting has been around what to put with certain files types within folders/directories - which may be related more so than anything else but just something about file extensions being associated incorrectly by some versions versus others? This did not cause us issues per se however since there were other ways found via trial-and error where one could upload documents directly from Word instead if having them uploaded separately first then linked together once downloaded would resolve many problems!
