Is it possible to download programs and install them on an external hard drive? If so then how do I do it?

Answer 1

during the first phase of instlalation, it should ask you if you agree to terms, agree and proceed, when you get to a window where it has a line like

C:\program files\programofdoom

you can change it to your external hardrive path, assume your External HD is drive Q

Q:\ProgramofDoom

from there continue the installation and it should work. unless it's a program that self extracts and does nothing afterward.

Answer 2

When you are installing programs, it usually asks where you would like to store them.

At that point, I create a folder and store them on my external hard drive.
