+## For developer
+
+You can reuse the `IrAttachmentActionDownloadMixin` on your
+favorite models::
+
+    from odoo import models
+
+
+    class StockPicking(models.Model):
+        _name = "stock.picking"
+        _inherit = ["stock.picking", "ir.attachment.action_download"]
+
+
+Then you can add an action button on list view line or on the action button
+(when multiple lines are selected) to download all files::
+
+    <odoo>
+        <!--
+            add a button on list view to download all attachement present
+            on the given transfert

+
+
+.. note::
+
+    Even you will be able to generate a zip file with multiple document with the
+    same name it's advice to overwrite `_compute_zip_file_name` to improve the
+    name. When a slash (`/`) is present in the path it will create a directory.
+    This example will create a directory per stock.picking using its name::
+
+        class IrAttachment(models.Model):
+            _inherit = "ir.attachment"
+
+            def _compute_zip_file_name(self):
