A backend over a directory of the file system, on the JVM.
A path below the root of the share is the file or directory of the same path below the directory. The backend keeps what it needs of its own in a directory named .webdav at the top, which no request reaches and no listing shows:
A PUT is written to a file in tmp and then moved into place, so a body that's refused or broken off changes nothing. A MOVE renames the file or the directory, properties and all, and a COPY goes through the handler's own copying. A new name can be 251 bytes long, so that its properties' file fits beside it.
An ETag is the size, the time of the last change and the inode of a file, where the file system has inodes. Each PUT makes a new file, so its ETag differs from the last one even within one tick of the clock.
Some paths count as nothing there, nor what's below them:
One process serves a directory, and nobody else writes to it, since a local user who swaps a directory for a link while a request is under way can make the backend write where the link leads.

The backend keeps what it needs of its own in a directory named .webdav at the top, which no request reaches and no listing shows: - props, the dead properties of each resource as an XML file, in a tree that mirrors the share, e.g. props/notes.d/a.txt.xml for notes/a.txt, and root-props.xml beside it for the root's - tmp, the bodies of PUTs while they're written A PUT is written to a file in tmp and then moved into place, so a body that's refused or broken off changes nothing.

Each PUT makes a new file, so its ETag differs from the last one even within one tick of the clock. Some paths count as nothing there, nor what's below them: - a symbolic link, wherever it leads, and a FIFO or a device - the backend's own directory by any name - a name that the file system takes for another, e.g. A.txt for a.txt on one that ignores case, as macOS's does, so a MOVE can't rename a file by its case alone One process serves a directory, and nobody else writes to it, since a local user who swaps a directory for a link while a request is under way can make the backend write where the link leads.

A backend over the directory `dir` (a path or a File), which must be there, with the `opts` below: - :namespaces, the aliases of namespaces in property names, the same as the handler's - :content-type, a function of a file's name that returns its media type or nil, by default URLConnection's guess from its extension It has every function of a backend but :copy!.
The name of the directory at the top of the share that the backend keeps for itself.
