Short for Dynamic Link Library, DLL is a file used with Microsoft Windows, Windows software programs, and Windows drivers. DLL files contain one or more executable subroutines that can be called by one or more programs and help software developers use Microsoft's or other company's routines to perform common tasks without having to re-invent the wheel.
