XF 1.5 How do I delete all PM except mine?

[Betclever]

Hello,

How do I delete all PM except mine?

I found those queries but what about my private messages?

TRUNCATE TABLE xf_conversation_master;
TRUNCATE TABLE xf_conversation_message;
TRUNCATE TABLE xf_conversation_recipient;
TRUNCATE TABLE xf_conversation_user;
UPDATE xf_user SET conversations_unread = 0;

Thank you

There isn't a way to do that.
