How 2 Cleanup Novell’s Border Manager?

I have notice that our Novell Proxy(Proxy Server)Server’s HDD amount is getting smaller and smaller. Is it posibble to cleanup the system’s contents without any proplem on the Proxy Server? Just like with “DISK CLEANUP” for Windows Server.

I also want to delete file on Novell 5 Servers, but I don’t know how to do it. Please help…

Thanks,
