DirectoryName

DirectoryName["name"] extracts the directory name from the specification for a file.

DirectoryName works differently on different computer systems.

DirectoryName["directory"] is normally equivalent to ParentDirectory["directory"].

DirectoryName["name", n] applies DirectoryName n times to name.

DirectoryName yields output appropriate for use in SetDirectory and ToFileName.

If name contains no directory specification, DirectoryName["name"] returns "".
