File | Save Workspace to File
Click Save Workspace to File on the File menu to save the current workspace to a file.
When you click Save Workspace to File, the Save Workspace to File dialog box appears. In this dialog box, enter the name of the file that you want to save the workspace as. Then, use the Save in list to navigate to the directory where you want to save the file, or select a specific file you want to overwrite. (The default file extension is .wew.)
Click OK to save the file, or click Cancel to exit.
