I am very surprised this question did not come up before. But I have looked in the archive and could not find it. With Bittorrentsync it becomes really possible to hold all the files I am not using in a single folder in a server somewhere, and then just download what I need. This would keep my laptop nice and empty and fast. Unfortunately such folder would end up being almost 1 terabyte, or more. I don't want to download the whole folder in my computer. But I know that it is possible to only download a single file with the mobile application. So it must be possible, at least in a theoretical way to do the same with the desktop application. Of course this would mean that through the desktop application I must be able to see the whole list of all the files, and all the directory structure, and the just ask to keep in this desktop synced a particular subfolder or some files. Is this possible? If not can I make a feature request? I think this would really increase the value of the application :-). Cheers, Pietro EDIT: grammar and little corrections
