Normally, the folders are synced to a folder named "Boxifier", located in your Dropbox account, but we released a new feature that allows our users to sync folders to Dropbox as top-level folders or as subfolders of a top-level folder from Dropbox. Here is an article explaining how to sync folders outside the Boxifier folder.
Licenses can be transferred during the first year since the purchase date. The 1-year license includes one free transfer. The lifetime license includes unlimited transfers. Please note that a transfer fee will be required if you ask for more than one transfer within a 18-months period.
