What is a DLL file? DLL stands for Dynamic Link Library. A DLL file is a file format used for multiple codes and windows programs. To put it simply, DLL files are external parts of running applications on Windows and other operating systems.

  • “Windows.dll not found.”
  • “This application failed to start because windows.dll was not found. Re-installing the application may fix this problem.”
  • “The file window.dll is missing.”
