Can I connect more than one Dropbox account?
Short answer: Yes, up to five Dropbox accounts, each with its own nickname and signed in separately. If the browser signs you in as the first account, sign out of Dropbox in the browser before adding the second.
Yes — up to five Dropbox accounts, each with its own nickname such as personal-dropbox and work-dropbox. They're signed in separately and every transfer uses the one you pick.
When adding a second account, make sure you sign in as the right Dropbox user in the browser — if Dropbox signs you straight in as the first account, sign out of Dropbox in that browser first, then click Try Again.
