title: Delphi Search path vs Library Path vs Browsing Path
body: <p>In Delphi, I can include a folder's source code by adding it to the project Search Path, or adding it to the Library Path.  The Search Path applies only to the current project, while the Library Path applies to any project opened with the IDE.</p>
  
  <p>Other than that, is there any functional difference between the Search and Library paths?</p>
  
  <p>My reason for asking: I have a folder X with source used by project A.  When I include that folder under Project A's search path, it says it cannot find a specific file in that folder.  When I include it under the Library path, then project A compiles fine.</p>
  
  <p>Until now, I was always under the impression that the only difference was that one was project-specific, and the other was global.</p>
  
  <p>While we're on the topic (and at the risk of making a fool of myself): What is the functional difference between "library path" and "browsing path"?</p>
