In other words, you can use a file tree wherever a file collection is required, but remember that a file collection is a flat list/set of files, while a file tree is a file and directory hierarchy.
To convert a file tree to a flat collection, use the link:{javadocPath}/org/gradle/api/file/FileTree.html#getFiles--[FileTree.getFiles()] property.
