Hello Everyone, bit of a odd, embarrassing, question here.

I got some bit coin a while ago, and I plan to hold on to it for a while. I didn't forget that I have it , I just kinda lost touch with the technology. and I am not sure how to access the coins now.

While I don't want to sell it today , I want to make sure I still "have" access to it, and can sell it when I want, or use it to buy stuff.
I stored it on a computer, that I no longer use, but I can still access the files( for now). I might have a wallet address.

The original program I was using required a large download, I think it was like 5 gig at the time, it was the block chain I think.


How do I go about "finding", and regaiing contorll of my coins ( I have some lite coin as well to )  - you can assume I am as noob as it comes.

Links to help guides are also appreciated.
Cheers.
