Since 3.1
WebDAV API allows user to use standard WebDAV clients for managing sandboxes content.
It allows specifically:
browsing directory structure
editing files
removing files/folders
renaming files/folders
creating files/folders
copying files
moving files
It is accessible on URL "http://[host]:[port]/clover/webdav".
Although common www browsers can open this URL, most of them are not rich WebDAV clients, thus you can just see list of items, but you cannot browse the directory structure with common www browsers.
