I have downloaded three or four programs and don't know how to open them. They are "F-engrave", "arduino", "ugs-platform-app" and others. I am assuming there is a way for opening them up. For example "arduino" If I right click the first option is "Open with archive Manager". Clicking on that gets me to "Reading arduino-1.8.10-linux 64.tar.xz". That takes me to "arduino-1.8.10" which says it is a folder. if I right click I get "open", or "Extract". Right click or left click "open" I get lots of choices but none of which installs the program. I could go on with the "extract" choice but I think I am doing something wrong.
