I have been in crypto for a few years and over time, changed computer several times, transferring entire C drive content every time.
My new computer has a smaller C partition and I'm trying to free some space. I just found out I have an "Ethereum" folder in User/AppData/Local that I've carried along all this time, and it weighs 22Gb!!
I remember when I first started crypto back then, I thought mining was required, and I know I tried something, but stopped after getting some error message somewhere that I couldn't fix. However, as I'm now finding out, my computer did download (and install? and/or run?) something that I've been carrying along this whole time, and now it's apparently weighing heavy on my resources.
Exploring further, that /Ethereum folder contains:
/keystore is (sadly) empty...
- /chaindata (22Gb)
- /ethash (140Mb)
- LOCK (file with no extension)
- nodekey (file with no extension)
What am I supposed to make of this? Should I just erase this? Am I sitting on a stash of something? I don't necessarily want to store ETH blockchain on my C drive, I need the space, but I can't decently erase this without making sure it doesn't have any value.
