My PRTG server is running out of disk space. I understand if I decrease the global setting for 'Historic Sensor Data' from 365 days, then my disk usage will go down.
However, I still want to keep 365 days for most of my devices. But I have a bunch of devices that I do not need to keep long-term.
I would like to know if there is any danger in me manually purging some of the deviceXXXX.prd files from the \Monitoring Database\yyymmdd\ folders? Will I cause corruption if I purge some of those files?
