Hans Wennborg wrote an in-depth article about Zip files, you can check it out over here. Created about 30 years ago using technology from the 50s and 70s, Zip files are among the most widely used file formats out on the web. But what's their history, and how do they work? Read the full article to find out.
I have been curious about data compression and the Zip file format in particular for a long time. At some point I decided to address that by learning how it works and writing my own Zip program. The implementation turned into an exciting programming exercise; there is great pleasure to be had from creating a well oiled machine that takes data apart, jumbles its bits into a more efficient representation, and puts it all back together again. Hopefully it is interesting to read about too..
