**Arguments**
|
|
|
|
- The `url` argument is just the url of the YouTube Video you're downloading.
|
|
|
|
- The `audio_only` argument determines if the video will be an `m4a` file or an `mp4` file.
|
|
|
|
- The `delete` argument will automatically delete the file after uploading it to Discord. If set to False, it will only save the file if you are a bot owner.
|
|
|
|
- The `subfolder` argument only does anything if `delete` is set to False, but it allows you to save to a subfolder in the data path you've set previously without having to change said data path manually."""
