I'm sure there is overhead so if the file is truly 8GB, splitting it in2 will probably result in a file larger than 4GB. You may need to split it into 3 parts.
That is actually a really good suggestion. 8GB is well within splitting reason.
My suggestion would be to find out the exact size in KB of the ISO (eg - 8GB exactly is 8,388,608 KB), because 7zip requires to specify the number of bytes PER volume (archive).
If you wanted to split and exactly 8GB into 2 files, you would put in the bytes number "4,294,967,296". That is the number of bytes in 8GB divided
by the number of files (2).
Remember that 1024 bytes = 1KB
To bring them back together, simply put the two files into the same folder on the destination drive, then extract.
