# FileTree

interface FileTree : FileCollection(source)

A `FileTree` represents a hierarchy of files. It extends FileCollection to add hierarchy query and manipulation methods. You typically use a `FileTree` to represent files to copy or the contents of an archive.

You can obtain a `FileTree` instance using fileTree, zipTree or tarTree.

The order of the files in a `FileTree` is not stable, even on a single computer.
