The reason I ask this question is that I have just done a major sort of my massive data CD collection trashing around 400 CDs in the process. Many were Windows XP programs which would be well past their best but there were loads of games that would probably be fun to play still while still others were educational ones such as DK multimedia. None of there programs will now install, I get a message telling me to contact the supplier for the correct 32 or 64 bit installer but I guess all the information and photos are still present on the CD, certainly I can see the photos but, of course the links to the information is missing. I am not complaining, I clearly had my use and they are a good few years old but it has left me wondering just how much more we will use if certain formats are not available to us in years to come. Will we reach a point somewhere down the road where .jpg of .tif are no longer supported and just what could we lose if this is the case?
