WebDAV servers support file actions through HTTP methods (GET, PUT, POST, DELETE, PROPFIND, PROPPATCH, MKCOL, COPY, MOVE) that enable users to perform operations such as creating, deleting, renaming, copying, and moving files or folders on a remote server.
For example, a user can use the PUT method to upload a file to a WebDAV server or the DELETE method to remove a file from the server. The PROPFIND method can be used to retrieve metadata about files and folders, and the PROPPATCH method can be used to update metadata on the server.
In addition, web-based clients or desktop applications that support WebDAV can be used to perform these file actions in a more user-friendly manner. These clients can provide features such as drag-and-drop uploading, file/folder syncing, and collaboration support to facilitate file management on a WebDAV server.
