Claim:
A computing device comprising a processor, memory and program code which, when executed by the processor, configures the device to: (i) display a user interface to each of a first user and a second user to share information, wherein each of the user interfaces comprises, for each of the first and second users, (a) a private section configured to display information about files or folders available for the user to share and (b) a common section configured to display information about files or folders shared with the user; (ii) share a file or folder selected, from the available files or folders, by the first user with the second user by (a) allowing the first user to identify the file or folder in the private section on the first user's interface, which is not viewable by the second user, (b) unlocking a protection mechanism of the file or folder to allow access to the second user, (c) storing information about the file or folder, without the content of the file or folder, in a common work place accessible to both the first user and the second user, and (d) displaying information about the file or folder in the common section on the second user's interface, wherein the second user can access the file or folder through the displayed information; and (iii) stop sharing of a file or folder to the second user that the first user has previously shared with the second user by (a) deleting information about the file or folder displayed in the common section on the second user's interface, (b) deleting information about the file or folder that has been stored in the common work place, and (c) locking the protection mechanism to rescind access to the second user.
