DLL files are basically a library of functions that are executed by a windows application. DLL files provide functions that programs can access by creating links to the DLL file. Programs establish either a dynamic or a static link to the DLL file in order to execute functions while running a particular program. Static links to DLL files allow the program to maintain a constant link to the DLL file while a dynamic link to a DLL file is created by a program only as it is necessary for the execution of the program.

DLL files typically contain information or functions that are used by multiple windows applications, either individually or at the same time. These types of files were originally created in order to reduce the operation requirements of windows applications, making them able to run on older systems where memory and hard drive space were extremely limited. Many different windows applications use the same sequence of code to run similar functions. By storing this code in a DLL file that can be accessed by several applications at once, not only are you able to reduce the space needed for the applications, but DLL files also increase the speed at which functions are executed.
