Restrict User to Delete/Attach File

i think a hook will work doc_events = { "File": { "before_udpate": "custom_app_name.custom_module_name.file.before_submit" "on_trash": "custom_app_name.custom_module_name.file.before_submit" } } def on_update(doc, event=None): # Custom code to be executed after the document is updated # 'doc' contains the updated document object if doc.attached_to_doctype and doc.attached_to_name: doc = frappe.get_doc(doc.attached_to_doctype, doc.attached_to_name)…

you can use on_trash method as explained in this and add your conditions in it
