Sorry that I sound like a noob. It’s because I am.
I was looking for a new browser and found ungoogled-chromium on the forum. I started the installation process using add/remove program to built it. I saw someone said that it took them 4 hours to built it. My poor 10 year old laptop with i3 M 330 processor was still working on it after 24 hours so I decided to give up. I just closed the add/remove program and restarted the system.
My question is how to remove the built files? I don’t see ungoogled-chromium in the programs (which makes sense because I stopped it in the middle). Do I need to remove those unused files?
