.ICD File Extension

An OpenGL driver that is responsible for implementing the entire OpenGL pipeline for a Windows game or application; intended for high-end video cards that include most of the OpenGL pipeline within the hardware.

NOTE: Programs that reference ICD files may produce the following error message:

The Filename.icd file is linked to missing export Dinput.dll:DirectInputCreateEx

If this error appears, Microsoft DirectX may need to be reinstalled to fix the problem.

Executable program encrypted with SafeDisc, a disc copy prevention program for Windows games and other applications; typically saved along with an .EXE file which loads the protected ICD file.

In order for a SafeDisc-encrypted program to run, the SafeDisc authenticator must verify the SafeDisc signature on the disc. After the disc has been verified the ICD file can be decrypted and run.

NOTE: Beginning with SafeDisc 2, the loader was integrated with the main EXE file, removing the need for the ICD file.
