Once I have created a snapshot, how do I restore it?
1. Click the Snapshot View tab in the Sources in Project window.
2. Click the name of the snapshot you wish to restore.
3. Select Project -> Make Snapshot Current from the Project Navigator menu.
Project Navigator replaces the files in the project directory with the files saved in the selected snapshot. Before the files are replaced, Project Navigator asks if you would like to create a snapshot of the current project. If you select No, the current project files are deleted and replaced with the snapshot version.
