Hello, I had a wallet with I think what is called bitcoin -qt I think it is one of the original bit coin "clients" I know that it takes a long time to sync cause it downloads all teh data when you first install it. anyway, I had this account on it, and I backed it up with a file name based on teh date of the back up -- something like "feb 4th" or something. I have that backup file, but I don't understand how to get it "back into" the bitcoin program.

I think I have to move it to a specific folder, but I might also have to re-name it.

please advise.
