Not that I'm aware of, it's persistent, no other files affected on the pc. It's more like knots will download the chain, and then it won't shut the node down just stalls when "do not reboot until this window closes" comes up. It never closes. Just sits for 24 hrs or more. So I'm forced to kill the program or force a reboot on the system and while the folder with the blocks are all there, I can see them, and the 600+GB of space taken up in the partition, knots still prompts another download of the chain. I'll delete the download destination files for it and all I can do is redownload the chain again after that. It makes no sense.
