What I did do a long time ago was to write a program that would look at the disk image on file and convert it to a complete directory structure. The trick is to find inode #2 and start from there. I do not know, but perhaps, if I look long enough in my archives, the program might even be sitting somewhere. > > We transferred the disk images to big single files.
