Improving text file reading speed in Xcode?

I'm currently working on a project that involves a lot of text file reading. I need to get the contents of the files into NSStrings so I can go and manipulate them further. What I'm using:

NSString *file = [[NSBundle mainBundle] pathForResource:fileName ofType:@"txt"];
NSString *fileContents = [NSString stringWithContentsOfFile:file encoding:NSUTF8StringEncoding error:nil];

It works well enough, but as my project grows so does the number of text files. I'm starting to think there should be a more efficient way of searching through the text files included in the project.

In many cases, I know exactly what file I want to search. I have the files organized into group folders based on when they need to be read. Is there any way to narrow the range of the initial file search? It seems like searching through the entire application bundle every time is pointless when I know where the files I need are on a more specific level.

Is there some way to search through groups as opposed to bundles? Can I somehow exclude certain files from the search? From what I can tell, defining custom bundles for this context would not be an appropriate use of the NSBundle functionality.

Have you looked at the method -[NSBundle pathForResource:ofType:inDirectory:]?
