You see, I have my photos extensively organized and have burnt them to two separate re-writable dvds. I have left enough space on each for additional pictures since I take so many. Now, this is my problem, for instance: I have a folder named "Events" on the disc where graduations, birthdays, etc. go in. I want to add a new file called 17th Birthday directly into this "Events" folder, but it will not let me. I would prefer to be able to use Windows Explorer to do this like with a CDRW. I don't understand why they have not made DVDRW's with this feature. In-CD from Nero screws with my drive, so I don't want to use that.
