Windows Dynamic Linked Llibrary

The DLL file is a Windows Dynamic Linked Library. A DLL is a file of code containing functions that can be called from other executable code (either an application or another DLL). Programmers use DLLs to provide code that they can reuse and to parcel out distinct jobs. Unlike an executable (EXE) file, a DLL cannot be directly run. DLLs must be called from other code that is already executing.
