A DLL (Dynamic Link Library) file is a collection of small programs or routines that can be called upon by executable (EXE) files or other DLLs. Instead of every application building its own code for common functions, they share these libraries, saving memory and disk space.

Never download a standalone DLL from a generic “DLL download” site unless you have absolutely no alternative and have verified the file hash against a known good source.
