Was ist eine .dll-Datei?

DLL (Dynamic Link Library) files contain code and data that can be used by multiple programs simultaneously on Windows. Instead of each program containing all the code it needs, commonly used functions are stored in DLLs and shared among applications. This saves memory and disk space. DLL errors like "missing DLL" are among the most common Windows problems, usually caused by corrupted installations, missing updates, or malware.
