We're on version 220.127.116.114. There are .dat files saved in My Documents\PRTG Traffic Grapher\ folder. There's a folder per day, and about 30 MB's of .dat files in each folder. It's filling my C drive. How can I move this? We do have it set to backup daily to a different drive, and to purge after 365 days. There's one annual report we run, so I assume that's why 365 was chosen.
