I just rebuilt a PowerMac G3 which was running OS 8.x (with Archicad 6.5) and upgraded it to OS 10.x (with Archicad 7.x). The upgrade involved backing up the existing Archicad 6.5 files (*.LAY and *.PM) onto a mini USB zip drive (FAT32 format). After the clean install of OS 10.x (and Archicad 7.x) the files were copied back from the mini USB zip drive to the PowerMac G3. The problem is that the files will not open up in Archicad 7. I'm not sure if they got corrupted during the backup to the USB zip drive (since it was FAT32 format) or there is a conversion issue. The *.LAY files actually don't have that extension on them, but when I add the extension they still don't open. Anyone have ideas? I have some of the files zipped up which I can send as an attachment. Thanks.
