How To Open DLL Files: A Beginners Guide to Opening Dynamic Link Library Files

You may need to know how to open DLL files.

Dynamic-link library (DLL) files are a type of file that you may need to access from time to time. They’re usually very specific, and only certain programs will be able to open them.

You might know these as something like “Dynamic Link Library Files,” or maybe something more condensed like “DynasoLinkFilev3.1”.

If you can’t get your program to open up that DLL file, read on for more information about how to open DLL files!

How To Open DLL Files

What is a DLL File?

A dynamic-link library (DLL) file is a piece of shared code that is used by programming applications. These files are often used to save time by reusing code and they are most often only compatible with the software that created them.

DLL files are used to store and run code that an application needs to run, but which is not the primary focus for that application. Since the file is shared across applications, it can be called upon by many different programs at once.

DLL files aren’t just for Windows computers, either. This file type can be found on Macs as well as Windows PCs. Knowing what a DLL file is can help you identify it in your computer, so you know what program created it.

You can then take steps to open it so you can use what’s inside, like a program you might not have access to otherwise.

How to Open DLL Files

There are two ways to open a DLL file, depending on which program created it.

If you know which application created the DLL file, you can try opening it directly.

If you don’t know, you can look inside the file to see if there are any clues about what program to use.

Step 1: Check the Folder Location of Your DLL File

Depending on how you are opening your DLL file, you will need to do this step differently.

If you are using the file directly through the program that created it, you should be able to go to that program’s folder location and search for the DLL file.

If you are searching for a DLL file that you don’t know the creator of, you will need to go through the file and look for clues. Look inside your DLL file and see if there is any text that identifies the program that created it.

Step 2: Install the Program That’ll Open your DLL File

If you know the program that created the DLL file, you can try to install the program and see if it will open the DLL file.

If you don’t know the program, but you find a file name inside the DLL file, you can try searching for that name online. If you are able to find the creator of your file, you can also try installing that program to open your DLL file.

Try installing the program, and then open the DLL file to see if it will work.

Step 3: Try Using a Third-Party App to Open Your DLL File

If you still aren’t able to open your DLL file, try using a third-party app to open it. Those types of programs are specifically made to open a wide variety of files, which can be helpful if you are trying to open a DLL file.

If you are able to open the DLL file with a third-party app, you can save it to your computer as a regular file. Now you can open it like any other file on your computer.


Opening DLL files can be challenging if you don’t know what program created it. Luckily, there are a few different ways to open a DLL file, even if you don’t know which program created it. You can try opening the file directly through the application that created it, or you can look inside the file for clues about what program created it.
