moving addon from one computer to another

[Leah Ann]

Hi!

First, thank you for reading this, and if you choose to help, thank you for your help!

I have an addon that seems to be discontinued but still works. I would like to know how to move it to my new computer. Actually, is it possible to move all of them in one slick move? It would save me the trouble of downloading and installing them all again.

Thank you!!
Leah
