Can't scan for "new files" (manually moved files)

Nextcloud version: Nextcloud Hub 9 (30.0.0)
Operating system and version: Ubuntu 22.04.5 LTS (Proxmox CT)

Hi,

i manually moved files (photos) from one folder to another folder, using the ‘mv’ command in the console. Now i realized that it didnt update the files and folders new structure in nextcloud.

I googled and found a way, i would have to add

'filesystem_check_changes' => 1,

So I added that to the file:

/var/www/nextcloud/config/config.php

>>Looks like that now<<
 <?php

>   'instanceid' => 'ocao6dsh82gl',
>   'passwordsalt' => 'XXXXXXXXXXXXXX',

>   array (

i rebooted the nextcloud proxmox ct, waited a little bit, but it didnt work. Then i found another way, i used:

sudo -u www-data php /var/www/nextcloud/occ files:scan --all

The result:

so, that didn’t work either, what can i do now? what is that locked file?

btw, my files (photos) are located here:

/Daten/Flow/files

Is the problem maybe that my files folder is not in my nextcloud folder?
