If somebody figures out how to accomplish this, I'll be able to not use different storage providers to be able to work that way.
Every new business relationship has the potential that a business partner wants to setup a user in their account. Dropbox is account centric, that makes it easier to have different browsers/browser profiles, and different storage providers to keep things separate and accessible at the same time.
How hard would it be to have Explorer folders that are individually authorized, like multiple FTP accounts can be different drives in Explorer, and NOT linked in any way?
Community, please share your tricks on this subject. The Dropbox app is of no help as it does not have the efficiency of Explorer.
