Dynamic link libraries or DLL files as we commonly know them are very useful piece of codes that almost every Windows based program uses today. The DLL files allow static libraries to be used quickly and neatly in a software program. DLL files comprise of binary functions, and there is a function lookup table used by the program to jump to a specific location in the file to load that particular function.
Many important and complex tasks are usually stored in DLL files, making the main program much smaller in size. Additionally, the main code also appears to be clean and readable while it only references the binary functions in DLLs. Complex tasks include calling graphical functions for 2D, or 3D, rendering or running a UI thread, or it could also involve computing hashes or doing encryption functions.
DLL files usually load up at the time of the DLL initialization process which occurs at the beginning when you load the software program. If a particular DLL file is missing, errors pop-up saying which file is missing and then you are unable to load the program. This program has appeared and angered us on several occasions, because it disallows us from running a programwe need.
Many tools used today employ widely popular libraries such as the Microsoft VC++, or the DirectX libraries for graphics rendering. The open source graphic library OpenCL and OpenGL also have their DLL files, and System drivers and ActiveX controls also possess DLLs. The list will go on and on because anything Windows based will use DLL files. The Dynamic link libraries do not just have DLL as their extension, but also, OCX is a common extension and so,it is the DRV extension which is indicative of system driver libraries.
Usually, we blame the operating system for any errors that arise because of the missing DLL files. It is possible that you might have tried to delete unwanted files manually because they seemed useless to you, but then you try opening some program and it will give you a bunch of missing DLL errors. It is even possible that you have installed a fresh operating system and have not yet installed the VC++ libraries or DirectX and then you try to load the program just to be presented with a bunch of errors.
Whatever your errors may be, there are ways to fix them. All you have to do is look out for the error and observe the file name that the error message displays. Most of the time, DLL errors can be fixed easily just by searching on websites like “Fix4Dll”(http://fix4dll.com/ ) for the file name displayed in the error and then downloading the specific file onto your computer to fix the error.
The problem with many DLL download sites is that they can make you download a malicious file in the name of the missing dll file, and then cause more harm to your PC. Instead of the actual file, your program will load functions in the malicious file and compromise your computer. Thus, you have to be careful about where you download these DLL files.
