SWF (pronounced as ‘Swiff’) is an abbreviation for Small Web Format. It is an Adobe file format that is used for vector graphics, multimedia, and ActionScript. It can contain both, interactive text and graphics. These animation files are mostly used in online games played using a web browser.

Adobe’s own products can create SWF files as well as other third-party software such as SWFTools, Ming, and MTASC. These files are mostly not supported by traditional media players and require either plugins or specific players to be installed.
Possible Ways to Open SWF Files
There are several methods to open SWF files ranging from command line interfaces to installing different plugins but we will only look at the most efficient and convenient ways to do so. Make sure that you have an administrator account and internet access. Chrome is also said to open SWF files but that doesn’t work in every case.
Prerequisites: Adobe Flash Player & .NET Framework
Most third-party software requires that you have Adobe Flash Player installed on your computer along with .NET Framework for you to play SWF files on your computer. These are the key ‘ingredients’ that most media players list as their requirement.
- You can download Adobe Flash Player from the official website and select the Chromium web engine option along with Windows 10/8.

- You can also download .NET Framework from the official Microsoft website. Since we will be running applications, you should download the runtime and install it on your computer. To be on the safe side, download both, the entire framework and the core.

Method 1: Installing SWF File Player (Windows)
There are numerous third-party players which run SWF files but SWF File Player ranks top amongst them. It is simple and gets work done with no hassle at all. You can also set additional parameters while playing the SWF file from your computer.
Note: Appuals is not in any way affiliated with any third-party software. The packages listed here are solely for the knowledge of the user.
