splitpath

    Splits a path in to volume, directory, and filename portions. On systems with no concept of volume, returns '' for volume.

        ($volume,$directories,$file) = File::Spec->splitpath( $path );
        ($volume,$directories,$file) = File::Spec->splitpath( $path, $no_file );

    For systems with no syntax differentiating filenames from directories, assumes that the last file is a path unless $no_file is true or a trailing separator or /. or /.. is present. On Unix, this means that $no_file true makes this return ( '', $path, '' ).

    The directory portion may or may not be returned with a trailing '/'.

    The results can be passed to "catpath()" to get back a path equivalent to (usually identical to) the original path.
splitdir

    The opposite of "catdir".

        @dirs = File::Spec->splitdir( $directories );

    $directories must be only the directory portion of the path on systems that have the concept of a volume or that have path syntax that differentiates files from directories.

    Unlike just splitting the directories on the separator, empty directory names ('') can be returned, because these are significant on some OSes.
