if you're trying to access a file within your application bundle, you need to get the full path to it: [[NSBundle mainBundle] pathForResource: FILENAME ofType: FILEEXTENSION]

This returns an NSString, which you can pull a UTF8String out of and pass to fopen.

You want

NSData's

+ dataWithContentsOfURL: or + dataWithContentsOfFile: for input

and

– writeToFile:options:error: or – writeToURL:atomically: for output

What you do with the data in between is up to you.
