Abstract

A computer implemented method and system enable users to share files in a server-less shared space. By providing access to such spaces via a visual presentation, the system renders content available for access by other group members. Access is sometimes provided through propagation of metadata or other uniquely identifying indicia associated with the shared space to all group members.

Claims

1. A method for updating a shared file in a computer network including a group of communicating computing devices in a peer-to-peer network, the method comprising

performing, at a first computing device, a file system operation on a shared file associated with a first file icon corresponding to the shared file displayed in a first shared space display area to generate an updated shared file;

creating, at the first computing device, metadata associated with the updated shared file;

directly propagating, by the first computing device to a second computing device that has permission, the metadata associated with the updated shared file;

obtaining, by the second computing device, the metadata associated with the updated shared file;

determining, by the second computing device, whether the updated shared file should be replicated on the second computing device, the determining based on a file replication setting of the second computing device, the file replication setting selected by a user of the second computing device, comprising;

determining, by the second computing device, that the file replication setting indicates an on-demand basis and piecemeal downloading, by the second computing device from multiple computing devices of the group, the updated shared file; and

determining, by the second computing device, that the file replication setting indicates automatic replication and automatically piecemeal downloading, by the second computing device from the multiple computing devices of the group, the updated shared file,

wherein the multiple computing devices of the group from which the updated shared file is piecemeal downloaded are selected based on a closeness of each multiple computing device to the second computing device, the closeness based on of at least one of;

IP address or least routing time;

displaying a second file icon corresponding to the shared file in a second shared space display area of the second computing device indicating that the shared file has been updated; and

displaying, by the second computing device, a third file icon corresponding to the shared file in the second shared space display area indicating that the shared file has not been updated when the updated shared file should not be replicated on the second computing device, wherein the third file icon provides an indication that an update to the shared file exists in the peer-to-peer network.

2. The method of claim 1, further comprising providing a user interface at the second computing device wherein:

the user interface includes the file replication setting, and

via the user interface, the user is enabled to select the file replication setting of the second computing device.

3. The method of claim 2, the user interface at the second computing device further comprising, a display contributor name with files setting, and via the display contributor name with files setting, the user is enabled to select whether or not a contributor name corresponding to the updated shared file is displayed with a filename of the updated shared file.

4. The method of claim 2, the user interface at the second computing device further comprising a member contributions setting, and via the member contributions setting, the user is enabled to select whether or not members of the group have permission to contribute any shared content to the group.

5. The method of claim 2, the user interface at the second computing device further comprising a new content setting, and via the new content setting, the user is enabled to select a time interval within which a given content is defined as being new.
