See my previous reply. Clearly there is a 7-zip implementation for
Object Pascal (delphi) that we could possibly use. Correct - "solid
archive" enabled (one stream for all files) makes a huge difference
with the final archive size. Good news is that even with solid archive
enabled, 7-zip allows reading a specific file without decompressing
the whole archive. Total Commander's 7-zip plugin allows for this. And
7-zip beat the CHM compression numbers by far (see numbers in my
previous post).
