Hi, I downloaded Smarterstats to test on a website. After configuration, import was triggered but I forgot to delete very old IIs log file so Smarterstats  created a directory for all years/months since 2015 in SmarterLogs\WebLogs\1. 

I was not able to see in both GUIs where I can tell it to clean/reduce/purge the years 2015 to 2018.

Thanks for your help
