slow to open the program

Hi I'm using ASGRD 2019 V 12.0.6342.1

a Few month after using it i noticed Slowness when open de program, the problem is the logs, then I had to erase all the logs.

I need to store All the connection History Logs, whats is the best method?, can I easily make a copy of these logs?, what if i need in the future make an inquiry of these copied logs?

thanks
