WebDAV stands for Web-based Distributed Authoring and Versioning. It's a way for you to store and share files over the internet. It's like having a shared hard drive that can be accessed from anywhere. You can transfer files to and from the hard drive easily, even when you're not in the same place. This makes it easy for people to collaborate on projects since they can be connected from all over the world, making it much faster to get things done.
