Abstract

A system and method for sharing items. A sharer may choose to share individual items, such as documents, contacts, and e-mails. To begin the sharing process, a user selects the items that are to be shared. The user then selects the sharees who the items are to be shared with, and the permissions that are to be assigned to the sharees. When items are to be shared, they are left in place on the sharer'"'"'s machine, while the system ensures that the permissions are set, and any security issues are handled so that the sharees are able to access the items. In addition, the details of the sharing transactions may be tracked and recorded for later review. The sharer may also have the system send a link to the sharee for directly accessing the shared items from the sharer'"'"'s machine. The sharee may also be able to query the sharer'"'"'s machine to see what the sharer has shared out with the sharee.

Claims

1. A method of sharing a plurality of items stored on a user'"'"'s computing device, wherein the plurality of items are arranged according to a physical file system structure of an operating system, the method comprising:

storing a plurality of items on a user'"'"'s computing device, wherein the plurality of items are arranged according to a physical file system structure of an operating system located on the user'"'"'s computing device;

storing in the operating system one or more values corresponding to operating system properties for each of the plurality of items stored on the user'"'"'s computing device;

creating via the operating system a data object corresponding to a virtual folder representing one or more of the plurality of items stored on the user'"'"'s computing device, wherein the virtual folder comprises a location-independent view that exposes said one or more items, and further wherein the location-independent view is based on metadata associated with the one or more items;

displaying via the operating system the data object corresponding to the virtual folder representing one or more of the plurality of items stored on the user'"'"'s computing device, wherein said virtual folder is navigable according to one or more arbitrary parameters independent of the physical file system structure;

receiving via the operating system a user request to share one or more of the plurality of items stored on the user'"'"'s computing device that are represented by the virtual folder with one or more sharees, wherein sharing the one or more items comprises allowing the one or more sharees direct access to the user'"'"'s computing device on which the one or more items are stored; and

setting permissions on the one or more shared items that are represented by the virtual folder to provide the one or more sharees direct access to said shared items stored on the user'"'"'s computing device, wherein setting permissions comprises;

verifying that an operating system file share exists from which a first shared item represented by the virtual folder can be accessed remotely; and

if an operating system file share exists, setting an operating system permission property on the operating system file share, wherein the operating system permission property is set so as to allow the one or more sharees access to the first shared item represented by the virtual folder.

2. The method of claim 1, wherein receiving the user request to share one or more of the items represented by the virtual folder comprises receiving a level of permissions to be assigned to the one or more sharees for the one or more shared items represented by the virtual folder.

3. The method of claim 1, further comprising determining that the user request corresponds to a protected item represented by the virtual folder that cannot be shared with the sharee, and providing a user notification in response to the user request indicating that the protected item represented by the virtual folder cannot be shared.

4. The method of claim 1, wherein setting permissions on the one or more shared items represented by the virtual folder comprises verifying that a firewall on the operating system will allow the one or more sharees to access the one or more shared items represented by the virtual folder.

5. The method of claim 1, further comprising recording details of the sharing transaction, including at least one of the shared items represented by the virtual folder, the one or more sharees, and a time at which the permissions were set.

6. The method of claim 1, further comprising sending a link to the one or more sharees in response to receiving the user request to share the items represented by the virtual folder, the link allowing the one or more sharees to access shared items represented by the virtual folder from a remote computer by directly accessing the user'"'"'s computing device.

7. The method of claim 1, further comprising receiving a query at the operating system from one of the sharees and providing to the sharee in response a list of all of the items on the user'"'"'s computing device that are shared out to the sharee.

8. The method of claim 1, wherein setting permissions on the one or more shared items represented by the virtual folder comprises setting an operating system permission property on a first item on the user'"'"'s computing device without setting an operating system permission property on a parent folder of the first item.

9. The method of claim 1, wherein each of the items represented by the virtual folder has the same value for an operating system property stored in the operating system.

10. The method of claim 1, wherein the one or more shared items represented by the virtual folder comprises a non-folder non-file item.
