What is a SWZ file?

A .SWZ file is primarily an Adobe Flash Player Cache File developed by Adobe Systems. Developers use these files to store signed Adobe Flex framework libraries, also known as Runtime Shared Libraries. This allows web applications to load faster because the web browser caches the .SWZ file locally. In rare cases, a .SWZ file can also function as a firmware update for satellite receivers using the ALI Corp STB chipset.

How to open SWZ files?

Most users cannot open .SWZ files directly by double-clicking them. Historically, the Adobe Flash Player web plugin or the Apache Flex SDK read these files automatically in the background. If your .SWZ file is a satellite firmware update, technicians use specific hardware utilities like SWZTool to install the update.

Inspecting files online

Because .SWZ files have multiple possible meanings, we recommend using viewer.online/swz to identify the actual format of your file. The platform analyzes .SWZ files to identify their exact format and creator software, shows which programs can open the file, and usually previews it.

Summary

Because .SWZ files use the known certificate2 format, viewer.online/swz can safely open and display them online, eliminating compatibility problems.
