In case of directory rewrite old files are not removed

[pmaxs]

I try to upload directory that already exists on server. Everything is OK, new files are created, existing files are updated. But files that exist in current directory and are absent in new directory are not removed. Option copyJoin is set to false. Is it OK?

My config (I use elfinder with laravel/backpack)

<?php
return [
    'dir' => ['uploads'],
    'route' => [
        'prefix'     => config('backpack.base.route_prefix', 'admin').'/elfinder',
        'middleware' => ['web', config('backpack.base.middleware_key', 'admin')],
    ],
    'roots' => null,
    'options' => [
        'copyJoin' => false,
    ],
];
