Searching for files
The Go To > Resource action in the Navigate menu 
allows you to quickly find a resource in the Workbench by searching resource names.
You can also do more complex searches for files in the Workbench. For example, 
to find all files that end with .xml:
  - On the main toolbar, click the
  
  
  Search button 
. 
  - Type 
*.xml into the File name patterns field and leave 
    the Containing text field empty. 
    (You can use the pull-down list to select *.xml if it had been previously entered.) 
  - Finish entering your search options, for example to scope the search to 
    specified working sets, and click Search.
 
  - The Search view displays the results of your search. Right-click on any 
    item in the Search view to open a pop-up menu that allows you to remove items 
    from the list, copy search results to the clipboard, or rerun the search. 
    To open one of the listed files, double-click it or select Go to File 
    from its pop-up menu.
 
If you close the Search view, you can return to it later by selecting
Window > Show View > Other... > General > Search.
