Is it possible to save a file in a custom folder inside NSDocumentDirectory

Question

Is it possible to save a file (any type) inside a custom folder in NSDocumentDirectory? I mean every time whatever I try to save I use this as resource file path:

NSArray *pathComponents = [NSArray arrayWithObjects:[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject], fileName, nil];
outputFileURL = [NSURL fileURLWithPathComponents:pathComponents];

or

NSString *imageDirectory = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) objectAtIndex:0];

And as a result it always save in the following directory,
~/Library/Application Support/iPhone Simulator/......./Documents/file.ext

But is it possible to save that file inside a custom folder like this:
~/Library/Application Support/iPhone Simulator/......./Documents/CustomFolder/file.ext.

If yes, Could you tell me details about the process?
Thanks in advance.
Have a good day.

Additional:

Here, Actually I save an audio voice record file. The name of that file came from current time. I want to save that voice record file in a custom folder.

Here is my code:

- (NSString *) dateString
{
    // return a formatted string for a file name
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    formatter.dateFormat = @"ddMMMYYY_hh:mm:ssa";
    return [[formatter stringFromDate:[NSDate date]] stringByAppendingString:@".m4a"];
}

// Set the audio file
NSArray *pathComponents = [NSArray arrayWithObjects:[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject], fileName, nil];
outputFileURL = [NSURL fileURLWithPathComponents:pathComponents];

In outputFileURL I save my recorded voice.

I try with this :

// Set the audio file
NSString *customDirectoryPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
customDirectoryPath = [customDirectoryPath stringByAppendingPathComponent:@"MyCustomDirectory"];

NSArray *pathComponents = [NSArray arrayWithObjects:customDirectoryPath, fileName, nil];
    NSLog(@"pathComponents %@", pathComponents);
    outputFileURL = [NSURL fileURLWithPathComponents:pathComponents];
    NSLog(@"outputFileURL %@", outputFileURL);

The folder is created with out any problem but the audio file is not save in that folder. Thanks.

Yes it is possible. You just need to create a folder inside document directory.

- (NSURL *)audioRecordingPath:(NSString *)fileName
{
    NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
    NSString *documentsDirectory = [paths objectAtIndex:0]; // Get documents folder
    NSString *folderPath = [documentsDirectory stringByAppendingPathComponent:@"/Recorded"];
    NSFileManager *fileManager  = [NSFileManager defaultManager];

    NSError *error = nil;
    if (![fileManager fileExistsAtPath:folderPath])
        [fileManager createDirectoryAtPath:folderPath withIntermediateDirectories:NO attributes:nil error:&error]; //Create folder

    NSString *filePath = [folderPath stringByAppendingPathComponent:fileName];

    return [NSURL fileURLWithPath:filePath];
}

Then fetch the folder everytime you want to store something and store into it.

Yes it's possible, you can just append the directory name after NSDocumentDirectory and then may be do something like

 NSString *customDirectoryPath = [NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES) lastObject];
 customDirectoryPath = [customDirectoryPath stringByAppendingPathComponent:@"MyCustomDirectory"]
 if (![[NSFileManager defaultManager] fileExistsAtPath:customDirectoryPath]) {
        [[NSFileManager defaultManager] createDirectoryAtPath:customDirectoryPath
                                  withIntermediateDirectories:YES
                                                   attributes:nil
                                                        error:&error];
