It's a simple question.  I've been doing this since it was calculators, read the IRS regulations every year yourself, pencil in your foundation then do paper returns in ink with no errors, copy for the client, and send by mail. I know it sounds crazy, but it was.  Tax pro yes, Geek "no".  Had to get a new computer downloaded and installed the last 3 years to keep history on clients. So when I do the memory stick to get from one computer to another do I transfer to the stick or copy returns to the stick.  Tranferring seems reasonable, but I need full returns, not just client info.
