if I delete the Dir, the Files can no longer reference the Dir

It's not only a question of deletion. The reference to Dir within File will disappear as soon as the Dir object gets out of scope, which is a Bad Thing™ 

use strict;
use warnings;
use Data::Dump;

my $file = Practice::File->new('foo');
{
    my $dir = Practice::Dir->new('bar');
    $file->add_dir($dir);
}
dd $file;

__DATA__
bless({ dir => undef, name => "foo" }, "Practice::File")
