Dynamic Link Libraries (DLLs) are resource files that run in memory when a linked program executable launches. If you try to remove a DLL file and receive an access denied error, you will need to unload it. Once a DLL file loads into system memory to provide resource linking it will continuously run until unloaded. You can use the Command Prompt to remove a DLL file from memory and allow deletion without receiving an access denied error.
