I keep all of my reciepts so I can do a search on the items name. When I find it, I just look for the filename listed on the reciept. I'm not sure if all of the reciepts (old one's) tell you what file you downloaded, since it seems they named them in a readable fashion at some point. For those, the date is good enough, since it tells me which CD to get out! After joining the platinum club, I started a spread sheet which has the order id, date, items name, filename and keep them all related pieces together. I was afraid I might forget that I had already bought something ( at the price for some of those items, it isn't quite as hard to make last minute purchases which could be forgotten later on) This might pay off later, since you have to have purchase numbers for certain upgrades (which can take forever to find, since my saved mail is kind of messy and quite extensive) eric
