This page has pointers to examples of ZIP files that use the “Reduce” compression method (methods 2 through 5). They might be useful as sample files, or just as evidence that such files exist.
These files are from a CD-ROM named Libris Britannia, published by Walnut Creek in 1993. It can be found in the following places:
All of the files use compression method 5. None use compression methods 2 through 4. That’s unfortunate, but with PKZIP you had to use a special option just to use Reduce compression at all, so I guess there was little reason not to choose the highest compression level.
Here’s the list. Lines with a “ | ” mean that the ZIP file is contained inside another ZIP file.
