Consider the following scenario. Using Internet Explorer 6, Internet Explorer 7, or Internet Explorer 8, you download a .ZIP file from a web site. Once the .ZIP file is downloaded and saved to your local machine, you attempt to open the .ZIP file. At this point, the following error message is displayed:

The compressed (zipped) folder is invalid or corrupted.


This problem may occur if HTTP compression is enabled for .ZIP files on the web server that the .ZIP file is downloaded from. When HTTP compression is enabled on the server, the .ZIP file is encoded before being sent to Internet Explorer. Once the HTTP-compressed .ZIP file is received by the client, Internet Explorer passes the .ZIP file directly to the program configured to un-zip the .ZIP file without first decoding the HTTP compression.
