Exit and Suspend
The Exit and Suspend command writes a Source Insight recovery file out and then closes Source Insight without saving any files. This allows you to exit Source Insight and save your edits without altering any files. Run Source Insight again to recover your edits.
Warning! Do not alter the files that Source Insight had open before you run Source Insight a second time to recover your changes. Source Insight’s recovery system relies on the original files being left unchanged.
