There are several actions for handling files and folders in the Finder. Most actions come with one option ready selected but you can use the pop-up to change to a different action. Each pop-up also allows you to choose Delete Dir, although that is not available as a separate action.
Click the File Chooser button on the right of an action to select an existing file or folder on disk. Option-click on the File Chooser button to show the currently selected file or folder in the Finder (assuming it exists already).
The actions
Note: The source path must be an absolute path (or a path relative to home ~). The destination path must either be a simple single path component (not ~ or /) or an absolute path. If it is a simple path component, then it is relative to the parent directory of the source path. This is particularly useful in the Move or Rename action, as you can, for example, rename from ~/Folder/Old Name to New Name.
