SEP 12.1.2: How to dicrease log files?

Hey guys,

It's been quite a while since my last post, this time I was wondering around the SEPM Console, and I noticed that our drive space is getting smaller and smaller. One way I found to trim the size down is to retain only 6 days of security defenitions which is good because it worked. Now here is my problem:

1. How can I trim the the logs too? I cant find it on the SEPM Console.

2. Based on my previous readings (KB and Forum) deleting files directly from the Symantec directory is not advisable, what's your take on this?

Thanks,
