Disable USB pen drives

I have windows XP and Windows 7 workgroup with 15 avid workstations. I don't want that users use pen drives and external hd because virus and so on. To control i have disabled the usb ports from reading pen drives. To do that  simply make the permissions on the following files set to Deny:

C:\Windows\Inf\Usbstor.pnf
C:\Windows\Inf\Usbstor.inf

You need to go tools folder options then view and disable "Hide protected operating system files (Recomended)"

Pure and simple!

Avid Media Composer Export Project

Hi, work all day with avid at a school. We have a Unity Server and 15 Avid Media Composer PC's. Sometimes students ask me to take the project they made to home. With avid is not so easy. I have to consolidate all media to a new drive and copy the project and have duplicated media and have to delete older and so on..There are a couple of payed options but now there is a free!
It's Automatic Duck Media copy works on mac and pc

New in Media Copy version 3.0 s the ability to read Avid AVP and AVB files-- those are Avid project and Avid bin files! You can use Media Copy as a project archive tool, read your Avid bins and copy all of the media those bins are using!

So a easy way to copy media!
