Alright, I have a bunch of .001 files (001,002,003,etc) and I searched around and read that WinRAR and 7zip can combine them, but that never works. I also found that they say that HJSplit is the tool to use. Now these .001 files are suppose to combine into a .iso file. I run HJSplit and it creates a file that has no extension, the right name but no extension. Now I even try to extract that newly created file which shows it trying to extract the .iso but it freezes and goes no where. I also tried giving the no extension newly created file a .iso to the end, but when I mount it, it gives nothing. What am I doing wrong, is there another tool out there?
