I was pinging my ISP with holding all samples in memory. So after pinging over a period of 5 days (changed the pingplotter.ini to 14 days max, thanks to your online tutorial) I decided to cut down the max in memory to 300000 samples and was surprised that even the auto save function only saved my 300000 samples, is there a way to append to the saved pp2 file so I would not loose my prior ping samples?
