- ( NSString * ) locateFileOnDesktop : ( NSString * ) fileName
{
    NSArray * directories;
    NSFileManager * manager;
    NSMutableString * path;
    
    manager = [NSFileManager defaultManager];
    
    directories = NSSearchPathForDirectoriesInDomains( NSDesktopDirectory, NSUserDomainMask, YES );
    path = [[NSMutableString alloc] initWithString : [directories objectAtIndex : 0]];
    [path appendString: @"/"];
    [path appendString: fileName];
    NSLog( @"%@", path );
    
    return path;
