Answer 1

In these situations I follow this approach:

First save your RootList.txt in Resources folder in xCode.You have nothing in your Documents folder, yet.

In the beginning of your applicationDidLaunch call, do:

NSFileManager *fileManager = [NSFileManager defaultManager];
NSString *docsDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];
NSString *path = [docsDirectory stringByAppendingPathComponent:@"RootList.txt"];
if(![fileManager fileExistsAtPath:path])
{
NSData *data = [NSData dataWithContentsOfFile:[[[NSBundle mainBundle] resourcePath] stringByAppendingString:@"/RootList.txt"]];
[data writeToFile:path atomically:YES];
}

Now, your file is in Documents folder at startup.
