Recently I upgraded Norton Disk Dr. to be compatible with System 8.1 (on a Mac 7100/80), having bought Norton 3.5.3 directly from Norton.
When I tried to do a Norton "sweep" on my hard drive, a message appeared saying Norton will not work with non-hierarchical files.
History: Previously I had run an Allsoft application which is designed to reduce file size on the HD, and it saved about 65 M on the hard drive. However, if I can no longer use Norton, a 65 M saving is not a worthwhile benefit.
The question is, "How can I restore the hierarchical file system to my hard drive?"
If I have to erase and re-install all of the software, OK, but I would like not to lose the data files. If I save the non-hierarchical data files to my external drive (not Allsoft converted, would they then converted to a hierarchical format, which could be re-implanted on the erased hard drive?
Thanks in advance for any help that comes this way.
