What is an AST file?
An .AST file can have many different formats depending on the software that created it. The most common use is a Game Audio Stream File used in Nintendo GameCube and Wii games. These files store music and sound effects.
Another major use is as a Game Engine Texture File for Farming Simulator 22 by GIANTS Software. In other cases, .AST files act as game asset archives for Electronic Arts (EA) titles, or as scene scripts for visual novel games.
Because .AST is a general extension, it also has non-gaming uses. For example, it might be an Amazon Kindle DRM voucher, a Cadence Allegro Gerber PCB list, or even a legacy ClarisWorks Assistant File developed by Apple.
How to open AST files?
Because the .AST file type has multiple possible meanings, it is difficult to know which program to use. For Nintendo audio files, users often use vgmstream or FFmpeg. For Farming Simulator textures, modding tools are necessary. If the file is an XML-based Civilization VI asset, a simple text editor works.
To save time, viewer.online/ast analyzes .AST files to identify their exact format and creator software. It shows which programs can open the file and usually previews it directly.
Converting AST files
Once you know what the file contains, you might want to convert it. If it is an audio file, converting it to a standard format like .MP3 or .WAV makes it easier to play. You can easily do this on convert.guru.
Summary
viewer.online/ast directly opens and previews .AST files in the browser. If you do not know the actual format of your file, our tool will identify it. This eliminates the need to install different software or troubleshoot compatibility issues.
