What are Dynamic Link Library Files?

DLL Files, or Dynamic-Link Library Files, are Microsoft's implementation of shared libraries in the Windows operating system. They contain instructions that can be called upon by programmers when developing Windows software. By enabling common functionality through a universally shared library, it enables faster and easier software development because programmers are not required to code everything from scratch.

You can't execute a DLL file on its own. They can only be called upon by another piece of code that is already running. Aptly named, they are dynamic in the sense that they are not always available in the memory — the data contained inside of them is only extracted when a program explicitly calls for it.
