The important thing for TZipFile component is that the archive format
must compresses every file separately. Otherwise you can't extract a
specific file without unpacking everything first.


And at the same time, that is its weak point for packing a large number of similar documents, like the LCL documentation. It only compresses one document at a time, so it cannot use the information of previous documents for compressing. So it is nice for on disk compression, but less valuable for distribution purposes, see also Marco's numbers.
