Step 1: Double-click the file.

Locate the AST file icon and double-click it. If you have the right program installed, it should open the file automatically. If it doesn’t, move on to Step 2.

Step 2: Look for another program.

If the AST file doesn’t open when you double-click it, you probably don’t have the right program on your computer. There are several popular programs that can be used to open a AST file. Try one of the three most common programs: Need for Speed: Underground Audio File, AstroGrav Simulation Data File, or Photoshop Separation Tables.

Step 3: Check the file type.

If none of the above programs will open your AST file, check the file type to make sure you have a program that can open that type of file. Most AST files are Settings Files, but there’s a chance it might be another type.

You can find this information in the file’s properties. On a Windows computer, just right-click the file and click properties, and look for the file type under “Type of File.” On a Mac computer, right-click the file and click “More info,” and look for the file type under “Kind.”

Step 4: Get help from a developer.

If you can’t figure out how to open a AST file, a developer can probably tell you how. Find the program you have in the table below and contact the developer of that program.

Program Name Developer Name
Need for Speed: Underground Audio File Electronic Arts Inc.
AstroGrav Simulation Data File AstroGrav Astronomy Software
Photoshop Separation Tables Adobe Systems Incorporated
Ability Office Spreadsheet Ability Software
AST Audio Stream Nintendo
Claris Works Assistant File Microsoft Developer
Astound Multimedia Microsoft Developer
Technics Sx KN 6000 Keyboard All Custom Memory File Microsoft Developer

Step 5: Find a universal file viewer.

The easiest way to open a AST file, or any kind of file, is to use a universal file viewer like File Magic (Download). You can use it to open many different file formats. If it’s not compatible, the file will just open in binary.
