I have an older version of FileZilla 3.28.0 I need to update to more recent version. I downloaded the file from: https://filezilla-project.org/ 2020-03-11 - FileZilla Client 220.127.116.11 released - I got "FileZilla_18.104.22.168_x86_64-linux-gnu.tar.bz2" I opened it with Archive Manager and got three directories. Now what? I don't want to install it, because I have dozen's of site related info stored in the current version that I don't want to loose. Tried running sudo apt update and upgrade but got nowhere. Help!' It's probably something stupidly simple but I'm blanking!
