Hi @tmilencovici,
The free version will reflect any new files/folders that are added remotely as placeholder files. This means they will not be downloaded automatically. You can right-click->sync on a folder, at any time, to kick off a recursive sync job to download everything in the specified path, however.

Apologies for any confusion.
Thanks!
