Awhile back I used SmartSync to free up disk space. I'm now trying to ensure all files are on the local disk rather than only online. Is there a way to accomplish this?
One idea: under preferences in the Dropbox.com settings I found an option to drop the Dropbox file extension, which "allows Dropbox to store files as online-only to save hard drive space." When I toggle it on without saving, I'm told "The system extension will be uninstalled and you’ll be signed out of Dropbox on all devices within the hour. When you sign back in, you can choose what folders to download from Dropbox.com. You will no longer be able to make files online-only." My issue with this is I have 200k+ files perhaps half of which are online-only and Dropbox has limits of file transfer/bandwidth that might prevent me from downloading them all.
