What is a CL file?
The .CL file extension most commonly represents an OpenCL Compute Kernel Source file. Software developers use the OpenCL standard, created by the Khronos Group, to write programs that run across different hardware platforms. A .CL file stores this source code in readable, plain text.
However, the .CL extension has multiple different uses. It can be a Cursor Library file created by Aha-Soft to store collections of mouse cursors. It is also used as a chat log file by messaging applications like WeChat and ICQ, an indexed resource file for games like Cross Fire, or a compressed ZIP package for Android themes.
How to open CL files?
Because .CL files are used by many different programs, the correct software depends entirely on the file's internal structure. You can open an OpenCL source code file with any standard text editor, such as Visual Studio Code or Notepad++. If the file is an Android theme package, it is actually a compressed ZIP archive. If it is a Cursor Library, you need specialized icon software from Aha-Soft to view the images.
