title: Tools to search for strings inside files without indexing
body: <p>I have to change some connection strings in an incredibly old legacy application, and the programmers who made it thought it would be a great idea to plaster the entire app with connection strings all over the place.</p>
  
  <p>Visual Studio's "current project" search is incredible slow, and I don't trust Windows Search.</p>
  
  <p>So, what's the best free, non-indexed text search tool out there? All it should do is return a list with files that contain the wanted string inside a folder and its subfolders. </p>
  
  <p>I'm running Windows 2003 Server.</p>
