Sice I posted the above, I have discovered that if I burn the files to CD with Roxio 9 drag to disk, they will not open on the older versions of Roxio either. I guess I will have to keep two sets of CDs, one for Roxio 4 through 7, and another for Roxio 9. The reason I don't want to use a flash drive, is that I am using these CDs for storage of information. I need to be able to add information to the files periodically. For example, I am using one to keep up with income from two sources. When the monthly amounts change, I need to be able to add this information to the file. If the file was made with Roxio 4 through 7, I can read it with Roxio 9, but I can't write new info to it, or delete from it. If the file was made with Roxio 9, it won't even open with the older versions. I can't believe that Roxio did this on purpose. Is there no way to add info to a CD made with Roxio 4, 5, or 7, when I am using Roxio 9 drag to disk?
