Jerome Fine replies: I forgot to ask - in regard to a file I would like to have! Since PUTR is designed for a DOS environment, it will (or so I understand) create (the actual command is FORMAT) files with a maximum size of 2 GBytes minus one cluster size. Since I am using a FAT32 system, I understand that I am allowed a file of a maximum of 4 GBytes minus one cluster size. Obviously, that is TOO large to download, but when I did a Zip, the compressed file was on 2 MBytes. Even better, when I used bzip2.exe, the compressed file was just over 1500 bytes. The example I used was a file with all zeros that was 2,147,450,880 bytes which was Zipped to 2,084,166 bytes. When I used bzip2.exe, the file was ONLY 1518 bytes. What I wish to have is a file that is all zeros and is exactly 2,147,483,648 bytes. I imagine that a Zipped file should also be about 2 MBytes and that a file compressed with bzip2 would be about 1500 bytes. Obviously a FAT32 file system is required. Thank you in advance to anyone who can help! I an an RT-11 addict and I want to spend my time with that operating system.
