of course now I`m a bit concerned because the near 160Gb progress I`d made running bitcoinD seems to have gone to zero now I`m running QT, which is only at 19Gb currently? I really hope I don`t end up downloading 2 copies of the blockchain!
Maybe the Snap version has a different location to save it's files. I'm not sure, never used it. It sounds like you started from scratch again.
