If you are a Dropbox pro or Business paid customer you are able remotely wipe your Dropbox folder from your computer or device, the next time it goes online. This is useful if your Mac has been lost or stolen to stop them from accessing your Dropbox files.
To be able to remotely delete the Dropbox folder you must be the admin of the Dropbox you wish to wipe. If you have connected your personal Dropbox to your work Dropbox, you can use remote wipe to delete your personal Dropbox folder from a device as well.
You must sign into your personal Dropbox account or your Dropbox for Business account. Click on your name at the top right of any page to open the account menu. Then select the settings. You will then see the security tab, find the device that has a Dropbox folder that you want to delete. Click on the X on the right. You will then have a pop-up window. Select the option ‘delete files from this computer the next time it comes online’ and then click the unlink button.
Another feature that the new update for the pro or business paid customers is the option that you can set an expiration date for a link you share to someone else. This will mean it will only be available for a certain period of time.
Unfortunately this is only available to customers that have paid for that type of an account and it isn’t offered for the free Dropbox account.
