Not to nitpick but might it be available in something a bit more friendly of a format? MacRAR can't make any sense of the file after Netscape spits it out and unpacking it on a PC and moving it to the mac kills the resource fork. I always liked Stuffit files. The bin files also seem to kill stuffit expander with a -39 error.
You might need to use that, or get a newer version of stuffit on the machine. That's your best bet and the only way to do it. Using an old stuffit version is the worst way of doing archives since Stuffit keeps changing their archive code
I know it's an old thread, but once I get my LC III up (converting an LC II to LC III) I am going to try to re-package these files in .sit. I will have to track down an old form of Stuffit somewhere (possibly eBay) or use a trial version or something if it exists. I will package it as old as I can.
The server I have running does use NTFS, so it shouldn't be a problem, but I will see what I can do.
