To do this, I clicked on several folders at once. To my horror, the downloaded folders only contained file names.. ALL THE FILES ARE EMPTY so when I uploaded them, I had NOTHING BUT FOLDERS WITH EMPTY FILES
Most files could be replaced from previous local backup but 67 text files created since the last backup are just gone! If folders must be downloaded one-at-a-time, you should say so. Now it's too late. The files can't be recovered. I can't tell you how much this infuriates me.
