I have this code in a method called from applicationDidFinishLaunching. It works in the simulator, but crashes on the iPhone. There are about 1,600 2KB mp3 files being copied in this operation. If I try to instantiate the app multiple times, it will eventually copy more each time until the app eventually will start without crashing. I am releasing everything I allocate. I have about 20GB disk space free on the iPhone. If I progressively comment out code and run it on the iPhone, the copyItemAtPath seems to be the suspect.

  NSError *error;
  NSString *component;
  NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
  NSString *documentsDirectory = [paths objectAtIndex:0];

  NSEnumerator *enumerator = [[[NSBundle mainBundle]pathsForResourcesOfType:@"mp3" inDirectory:nil] objectEnumerator];

  NSArray *temp = [component componentsSeparatedByString:@".app/"];
  NSString *file = [NSString stringWithFormat:@"%@", [temp objectAtIndex:1]];
  NSString *writableAudioPath = [documentsDirectory stringByAppendingPathComponent:file];
  
  
  BOOL success = [fileManager fileExistsAtPath:writableAudioPath];

      continue;

      success = [fileManager removeItemAtPath:writableAudioPath error:&error];
