Using Ubuntu 20.04 - I 'installed' a program (for Ubuntu) by extracting from a tar file (apparently the only way to 'install' it) to its own folder on the desktop, and it has a launcher shortcut within that folder which points to an executable text file (also within the desktop folder). Both the launcher and the executable work as expected, but I do not want this folder cluttering my desktop. I have looked at other similar questions and answers but none of those resolved my problem, although some addressed the same/similar issue.
Question 1: How can I move the program folder to where it SHOULD be located instead of on the desktop without breaking anything? Tried moving it to usr/share/ (where all other apps appear to be) - "permission denied". (Do I need root privelege? How do I get that?)
Question 2: Once it is in the right place, how do I get it into the main menu so I do not have to go looking for it deep inside the system when I want to use it?
