Based on a versioned item (already committed or scheduled for addition) in the working copy, you can generate patches that contain the local changes, the differences between a specific revision of that item and the item itself, or differences between the pristine item and another item from the repository. There are four options for generating a patch based upon local items.
To open the Create patch wizard, use the
