Edit fla file

Hi
I am new in this and trying to learn flash, how can i edit fla file, i have the orginal file

I’m assuimg you have Flash 8…if so, open Flash then select File, Open and navigate to the fla.
You can open all fla’s that are of the same, or a previous version. So you can open fla’s that are made in Flash 4, Flash 5, MX, MX Pro…but you won’t be able to open an fla that’s made in CS3.
