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.

My first thought was to create a batch file that deletes all of the definition files and schedule it to run periodically. The only trouble is that for the virus definition update process to work properly, the *last* definition file must be present e.g.

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.

I'd prefer to do this in a batch file if possible, rather than in Fox.

Anyone have any ideas?
