DLL File Type

- The quick facts

What are DLL files and how to open them

Are you having problems opening a DLL file or just wondering what they contain? We explain what these files are used for and show you software that we know can open or otherwise handle your files.

What is a DLL file?

DLL files, also called Dynamic Link Libraries, contain a collection of executable functions and information that can be used by a variety of Windows programs. A .DLL file cannot run on its own. It is loaded and used by a program executable (EXE file), so you should not try to run them on their own. If you are getting DLL errors, we strongly suggest you check your PC for errors and malware. It could also be that you installed a program that accidently replaced a newer version of a DLL file with an older one, causing other programs to crash or display DLL errors. At File.org we strongly recommend that you use DLL-Files Fixer to repair your damaged system files. It is the only program we have found of its kind that can actually repair your damaged files by replacing them by the originals!
