WebDAV stands for "Web Distributed Authoring and Versioning." It is an extension of the HTTP protocol that allows users to collaboratively edit and manage files on remote web servers. By enabling file manipulation over the internet, WebDAV makes it easier for users to upload, download, and organize documents directly from their web browsers or applications. This protocol supports various features like file locking, version control, and metadata management, enhancing the way users interact with files online. Many cloud storage services and content management systems utilize WebDAV to provide seamless file access and collaboration, making it a valuable tool for both individuals and organizations.
