Thanks brother


I have 700 plus folders

How to delete all?

Try this  * but not working

*   3   1-31   1-12   0-7   rm -f /home/u44173*****/domains/domain.com/public_html/oc-content/uploads/*/*.jpg

I guess with next cron it will work (separate all folders with comma) .... Maybe there is a better way than this but it's the first one i could think of....
*   3   1-31   1-12   0-7   rm -f /home/u44173*****/domains/domain.com/public_html/oc-content/uploads/{1,2,3,4,5,6,7,8,9,10,11,12,13,14}/*.jpg


Such amount should be managed from command line

You will have folders 0, 1, 2, 3...

Finally a solution found to clear all jpg files with directadmin cron. it will delete all files jpg in all numeric folders starting from 0,1,2,3, etc.... folders with names inside the upload directory stay untouched.

For DA  cron is

/usr/bin/find /home/u45******/domains/do***.com/public_html/oc-content/uploads/ -mindepth 2 -maxdepth 2 -type f -regex '.*/[0-9]+/[^/]+\.jpg' -print0 | xargs -0 /bin/rm -f >/dev/null 2>&1

This works easier than create a cronjob for every folder as it was before :-)
Enjoy

Next was a DAO to set item_resource table to set s_extension to webp... To do this create a php file called photowebp.php in your public_html directory.
Use code:
<?php

if (php_sapi_name() !== 'cli') {
    die('Access denied.');
}

define('ABS_PATH', dirname(__FILE__) . '/');
require_once ABS_PATH . 'oc-load.php';

require_once ABS_PATH . 'oc-content/plugins/webp_images/model/ModelUP.php';
$modelUP = ModelUP::newInstance();

// Attempt to update item resources
try {
    $modelUP->updateItemResource();
} catch (Exception $e) {
    // Handle the exception if needed
}

?>

Then in folder oc-content/plugins/webp_images/model create a php file named ModelUP.php with code:
<?php
class ModelUP extends DAO {
    private static $instance;

    public function query($sql) {
        return $this->dao->query($sql);
    }

    public static function newInstance() {
        if (!self::$instance instanceof self) {
            self::$instance = new self;
        }
        return self::$instance;
    }

    function __construct() {
        parent::__construct();
    }

    public function getTableItemResource() {
        return DB_TABLE_PREFIX . 't_item_resource';
    }

    public function updateItemResource() {
        $sql = "UPDATE " . $this->getTableItemResource() . " SET s_extension='webp' WHERE s_extension IN ('jpg', 'png', 'gif', 'jpeg')";

        $this->query($sql);
    }
}
?>

Call file photowebp.php when you want to run it using cronjob in directadmin with command:

/usr/local/bin/php -q -f /home/u441*****/domains/domain.com/public_html/photowebp.php >/dev/null 2>&1

Your done :-) Enjoy
