Dragan's suggestion is viable. But if you're still interested in a batch file, I would look at WSH.

>I have a client with a W2K Server. They have the Trend Micro OfficeScan product installed on its system (C:) drive. This product downloads large (~17MB/day) virus definition files to a specific folder on C:.

>Trouble is, they don't have a lot of free space on C:, so within a couple of months their C: drive fills and their server crashes. It would be nice if Trend would clean up old definition files itself but it doesn't seem to do so.

>LPT$VPN.456
>LPT$VPN.457
>LPT$VPN.458

>LPT$VPN.473
>LPT$VPN.474
>LPT$VPN.475  <-- Latest one, this file must not be deleted

>It's simple to make a batch file that deletes *all* of the update files, but much more challenging to write one that deletes all of them except for the very last one.
