How to prevent email attachment from saving directly onto USB devices?

Discussion created by Cw on Jan 7, 2011
Hi,  My company is using DLP 6.0 (previously known as Orchestria 6.0). I understand that the client file system agent can only apply policy to files or documents copied to USB devices using DOS commands or Windows Explorer. Is there a way that i can apply policy to email attachments saved directly onto USB devices?   When I click on the email attachment  from my email, i can choose to save it onto my local disk or USB drive. If I save it onto my local disk, it would not fire the policy. However if I save it onto a USB drive, it should fire the policy.    Appreciate if anyone can help.    Thanks.Regards, Cw
