my @new_path = join "\\", @path[0,5,6];

@newpath should not be an array variable since the result of join is a scalar. That should be $newpath. If you want to pass that value to a subroutine, do this:

...
    $new_path = join "\\", @path[0,5,6];
    process_directory($new_path);
...

sub process_directory {
    my ($path) = @_; #$path gets the value from $new_path above
    ....
}
