".gz" files

Jerome Fine replies" I finally had an hour today and did a "Burn Image" to a CDRW from the "rt11freewarev2.iso.gz" file (687,282,673 bytes) that was the result of the download from the classiccmp site. Unfortunately, Nero Burning under Windows 98 made an exact duplicate of the file to the CD and the result is therefore, obviously hopeless, as far as what is actually needed to set up the correct ISO file structure on the CD, let alone the correct RT-11 file structure in RT-11 partitions 13 to 19. So I am again back to square ONE! The ".gz" files at the classiccmp site do NOT behave when I do the download since the uncompress occurs during the download. Under Netscape 4.78/Windows 98, I click the menu item "Save link as ..." and follow through by Save after I select the directory into which to place the downloaded file. But I don't end up with the actual file from the classiccmp site. Rather that expanded file is the result which "Nero Burning" just copies to a CD which ends up being useless. Any other suggestion? I am getting a bit desperate - well maybe not desperate, but I am really confused and perplexed. Sincerely yours, Jerome Fine
