I guess what I was trying to say is that if your save to location folder is the same as your sharing folder location it is the same folder. As soon as you complete a download it will be immediately shared for uploads. One folder no need for a second folder with identical files.
I use 2 different locations so that I may be able to preview the dowloaded files to make sure they are what I wanted ( not mistitled and totally different and unexpected) and of good quality then tranfer them, so only good quality files are uploaded.
But I think this answers your question better
