    [archiver encodeFloat:y forKey:@"y"];
    [archiver encodeFloat:z forKey:@"z"];
    [archiver encodeObject:name forKey:@"name"];
    [archiver finishEncoding];
    NSString* filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"XML Position"];
    BOOL result = [data writeToFile:filePath atomically:YES];
    if(result)
        [self   updateTextView:@"success"];
    [archiver release];

On the device, the corresponding code:

NSString* filePath = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0] stringByAppendingPathComponent:@"XML Position"];

gives the following value to filePath:

/var/mobile/Applications/<<UUID>>/Documents/XML Position

where UUID is the unique application identifier.
