What is a .ICD file?
The .ICD file extension stands for Installable Client Driver File. This type of file is a special kind of executable program, which means it's designed to perform actions or run a series of commands on your computer. What makes .ICD files unique is that they are encrypted with SafeDisc. SafeDisc is a technology used mainly for Windows games and some other software to prevent illegal copying of the disc. Essentially, it's a way to protect the software from being pirated.
When you see a .ICD file, it's usually not alone. It often comes with an .EXE file, which is a more common type of executable file. The .EXE file's job is to load the .ICD file, which contains the protected part of the software. This setup helps keep the software secure while allowing it to run on your computer.
To open or run a .ICD file, you don't need to do anything special yourself. These files are designed to work automatically when the software or game they are part of is used. They were originally created with a technology called Macrovision SafeDisc. When the correct CD or DVD (the media) is in your computer, the .ICD file should run as intended without you having to open it manually.
However, sometimes there can be issues. For example, if there's a problem with the .ICD file or the software trying to use it, you might see an error message like this: "The Filename.icd file is linked to missing export Dinput.dll:DirectInputCreateEx." This error suggests there's a problem with Microsoft DirectX, which is a collection of APIs (Application Programming Interfaces) used for handling tasks related to multimedia, especially game programming and video, on Microsoft platforms. If you encounter this error, reinstalling Microsoft DirectX might solve the problem, as it will replace any missing or corrupted files that are causing the issue.
In summary, .ICD files are part of a system designed to protect software from being copied illegally. They work automatically when everything is set up correctly, so you typically won't need to open them manually. If there are errors, they might be related to other parts of your system, like DirectX, and fixing those should resolve the issue.
