Abstract
A method, system, and manufacture for securely broadcasting shared folders from one client device to other client devices and synchronizing the shared folders over a local area network. A first client device, associated with a content management system, generates a secure identifier for a shared folder, using a shared secret key that is associated with the shared folder. The first client device announces the secure identifier over a local area network to other client devices on the local area network including a second client device. The first client device receives a synchronization request for the shared folder from the second client device. After authenticating, using the shared secret key, that the second client device has authorization to access the shared folder, the first client device synchronizes the shared folder with the second client device over the local area network.
