Q:

Where to store unzipped application files

I have used apt-get a lot to install programs, but I just recently wanted to use Abricotine markdown editor. The way it says to install it is by downloading and extracting a zip file. I do that, and the program has an executable file there along with some other folders and stuff.
I'm new to Linux in general, so could someone tell me where I should move these files and folders? I tried using the terminal to move the whole unzipped directory to /usr/shares/, but then when I search the computer (I'm on Ubuntu 16.10) it doesn't show up.
Where should these files go?
Thanks

A:

Unity Dash uses locate, so to reindex a program in /opt/ try 
sudo updatedb -U /opt/

To get only the program to show up, with a nice icon and everything, you'll have to create a .desktop file. Also see adding program to launcher.
