Apps :: How to install apps if no internet aveilable

Thanks for your answers, I did what you suggest, and worked fine, the problem is that the app. I'm interesterd in (Dosbox) needs to load a config file when launching this app. and I don't know where to put that file. Or better, I can tell dosbox where to find it, but in the shortcut or script that launches dosbox, and I don't know where to find them.
Perhaps you can help me.

Thanks again.

Galbi.
