-<h1>Searching External Files</h1>
-
-<p>C/C++ search, by default, will only search your workspace. 
-If you wish to search external files that are included by files in your workspace but don’t reside in your workspace, 
-you must enable external search markers.</p>
-
-<p>When a match in an external file is now found, it will be linked into your project and you will be able to open the match from the search pane as usual.</p>
-
-<p>When a project is closed, or the workbench is shutdown the links are removed. </p>
