.DLL files

Shared files are usually DLL files or "general purpose" files that more than one program can use.

DLL (Dynamic Link Library) files are basically "support" files for software.

They work like this: Let's say a program needs to perform an operation. Rather than all the coding being built into the program, it uses a particular DLL file that, with a simple call, can perform the operation for it. This saves lots of programming time, especially since many of the common DLL files are already installed with Windows.

Like several programs may use the same .dll file, many problems come from having a corrupt or deleted .dll files.

We have all seen the error message "Could not find ***.dll" and wondered how to get the file back. Here is the place to go for free downloads of the most common files that are missing from your computer.

Simply type your missing file name into the search box to find if it is available, then download it. You can also go to the "dll-files downloads" page and scroll down the alphabetical list to find the file you need.

I have found this site very useful.


Most .dll files are in C:\Windows\system 32, but they are in all of your programs. All programs need .dll files.
