What is a ZIPX file?

A .ZIPX file is a ZIP Extended Compressed Archive file.

Files with the .zipx extension are compressed ZIP Extended archive files - a newer type of ZIP file.

When a .zipx file is created, data is compressed to reduce the file size. Multiple files can be combined into a single ZIPX file, making it easier to upload, download or email the files. For example, if you have 5 big documents to email to the same recipient, you can create a ZIPX file and get a single, smaller file that is easier to email.

The ZIPX format was introduced with WinZip version 12.1. It introduces four new compression algorithms (ways of reducing file sizes) to the ZIP file format, which is why WinZip owner Corel Inc., after pressure from users and competitors, decided to name the files ZIPX instead of ZIP. The first version of WinZip using the new algorithms broke compatibility with other ZIP compression tools because it used the .ZIP extension for ZIPX files, causing competing tools to fail to extract data from those files.

Today most modern compression tools support the ZIPX, like, e.g., BitZipper.
