I had a CD-R that has folders A, B, and C directly on the drive. I opened a .drf file in Firefox from folder An on the disc. While tying to save an image to my computer I accidentally selected folder A from the disc. I canceled as soon as I realized what it was doing and all seemed fine as I could access folder A. I then ejected and used another disc but not when I put in the first disc I can no longer access folder A (while folders B and C are still accessible on the disc, as well as all files that were not in folders).
Any ideas on what might have happened or if you know any utilities where I would be able to access the previously saved files / open that folder? Right now the Folder name is on the disc but it just says "File" under type and 0k. No date modified. Both the computers I used to create the CD and open the CD were running Windows 7, although they were different computers.
