How can I change the expiration date of the link I want to share?

When you click the Share button next to a file/folder and select Send Link, a new window pops-up. If you want to change the expiration date of the shared link, click on the downward arrow next to the set expiration date. You can choose your preferred expiration date out of these options: 1 hour, 1 day, 1 week, never, or set a custom expiration date. Choose one option and click Ok when you are done.
