Filez (http://www.filez.com) claims to be the largest file site, and it's probably the best-organized. You can use its subject categories, or browse the top 20 applications or new files posted in the past 20 days.
A search for "restaurant" under the heading "Windows" yielded one hit: a compressed file called McDonald's Restaurant.zip. A search for "compression" under "Windows-All" resulted in 13 utilities for various file formats, but no PKZIP or WinZIP. (I did find WinZIP listed as one of the Top 20 applications.) A search for "pyramid" under "Graphics" produced 20 files with .jpg and .gif extensions, two common graphics formats.
