What happens when you lose a DLL file?
Dll files are essential to the function of programs within a Windows operating system. They may or may not be backward compatible with previous versions and operating systems, which makes them important files for the computer and the programs you use. Dll files are Dynamic link library files and just like the name says, they are a library of files, which create small programs. These small programs have a variety of purposes.
Primarily the purpose of a DLL files is to act as a call function response. Basically, what this means is that commonly shared aspects of programs, things like open, save, print instead of being placed within the application and rewritten over and over again for every single program that uses it are placed in a “library” within the operating system. Then all the programmers of the program being executed need to do is write what is called a call function. The call function activates the DLL file and asks it to run. IT is then placed into RAM and the function is executed. Once the function requested is complete the DLL file stops executing and is removed from RAM.
DLL files are not just used by various applications but also used by the operating system itself. For example, the Kernel32 DLL files. This set of files deal with the functions of memory and various other operating system necessary processes. This is why the famous blue screen appears if a kernel32 DLL file is found missing in the operating system. Luckily restoring these files is usually easy. It simply involves a repair of the operating system or application that the file is attached too.
Most of the time if a dynamic library file is found missing with a program the program will not run or it will an error each time that particular function is requested will be received. Depending on the program, this may or may not be a problem. However, missing library files do indicate a system destabilization and need to be corrected in order to destabilize the program or system.
These files are essential to many functions and when these files are missing or damaged essential functions are left unable to be executed within the system. Unless you trained in computers, it is probably a good idea not to access the dynamic library files or mess with these files in anyway. If you find one missing run the windows operating system repair function from the operating system disk to see if you can correct the problem if not have someone trained or knowledgeable assist you.
