What is a CLT file?

CLT files mostly belong to VisualBoyAdvance.

The CLT file extension can refer to several distinct file types.
In many cases, it is a cheat list text file that holds game cheat codes for Game Boy Advance titles. Such files are used with emulators like VisualBoyAdvance and related tools. For more details on these cheat files, see NGemu.

Other CLT files include:

  • Cheat Codes: Files that list codes to modify game behavior.
  • CNC Lathe Toolpaths: Files that contain instructions for CNC machines, used with software such as PowerMill. More info is available at Autodesk PowerMill.
  • Crossword Templates: Files serving as client or clarity templates for the Cryptic Crossword Compiler.
  • Desktop Layouts: XML-based files that define layout settings for design applications like ConceptDraw PRO. Details can be found at ConceptDraw.

FilExt.com note: Examine the file in a text editor; markers such as XML tags or UTF-16 encoding may indicate its specific purpose and guide you to the right application.

How do you open CLT files?

You need a suitable software like VisualBoyAdvance to open a CLT 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 CLT file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a CLT file directly in the browser:. Just drag the file onto this browser window and drop it.

CLT file extension format:

Every file has a defined file format, i.e. how the data is arranged in the file. A file format is determined by the file extension and signature, so JPEG images have the extension .jpg and the first bytes in the file are ÿØÿ. Frequently, however, one file extension is used by different programs for different file formats, and one file format for different file extensions. So a detailed analysis of a file is vital in order to determine the format and the associated program. Below you will find our evaluation of the CLT files:
