What is a WSZ file

WSZ files mostly belong to Winamp. WSZ files mainly serve as Winamp skin files. They are actually ZIP archives that bundle graphic and configuration files to change the look of the Winamp media player.
Some WSZ files use zlib compression. These files act as data containers for Winsteps data files, also referred to as compressed Mplus data files. This use is common in statistical data analysis. For more on this usage, see this page.

The Winamp skin version stores images, layout info, and style files.

The zlib version holds data for statistical applications.

You can often change the .wsz extension to .zip to open the file with any standard archive utility.

FilExt.com tip: This dual-use format makes WSZ files both a tool for customizing media player appearance and a container for compressed data.

How to open WSZ files

You need a suitable software like Winamp to open a WSZ file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your WSZ file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a WSZ file directly in the browser:. Just drag the file onto this browser window and drop it.
