Your system's operating system created all different DLL files found in your system's local drive, but along with them, a different program can also install them. Thousands of DLL files are there created by the different programs on any of the operating systems.

Applications can automatically use these DLL files without any requirement for the user's input. Data saved in these DLL files can only load when the program itself uses that file, which shows the data that does not always load in the memory. It permits the application to use way less memory as it doesn't require loading the DLL files until it is using them actively.
If your DLL file is updated, all the applications that use the functionality of that DLL file will also be updated as well—providing the ability for programs to upgrade without reinstalling or rebuilding the application.

Steps to Open DLL file extension

To open the DLL file, you can use Windows Visual Studio Application.
Here are the steps are given below for how to use Windows Visual Studio Application to view the file:
1. Tap ...
... on the Search Bar in the Start Menu or on the taskbar.
2. Type Visual Studio in Search Bar and hit the Enter button.
3. Once in the folder, tap the icon named Developer Command Prompt.
4. As the Command Prompts gets loaded, type the “ILDASM.exe” and hit Enter key.
5. Then drag and drop the DLL file that you wish to open and view into the command prompt window.

Methods to Open DLL Files

DLL files can open by using two different methods. With the help of which files can easily open and viewed.
1. By Using DLL Files
2. By Decompiling DLL Files

Method 1: By Using DLL Files

1. Understanding DLL files
A DLL file is the windows file used by the programs to call upon the existing functions. They permit windows as well as other programs to gain functionality without having built-in functionality.
• These files are an important part of Windows programming and lead to sleeker, more efficient programs.

2. Knowing that the average number of users don't require to open and view DLL files
Often DLL files exist in the background for most of the users. Programs will automatically install them, and moving them can cause serious problems with your systems.
• Sometimes during the installation of the community-made programs, you may be asked to place the DLL files in certain locations. Ensure that you trust the application before following the instructions because DLL files can also be malicious.
• If you are interested to learn how DLL files get constructed, then see the next section.
3. Register new DLL file
If you are required to copy the DLL files into a folder manually for a program to use, you may need to register the Windows Registry file before using it. Then refer to the application’s documentation to examine if you need to perform this step.
• Firstly, open the Command Prompt from Start Menu or simply pressing the Windows Key + R and then type cmd. Search the location of the new DLL file.
• If you use Windows 7 or the newer version of Windows, then open the folder containing the new DLL file, then hold the Shift key and then right-click in the folder, and then select the "Open command window here" command. After selecting the Command Prompt will directly open to the folder.
• Then type regsvr32 dllname.dll and then hit the Enter Key. On typing this, it will add your DLL file to the Windows Registry.
• Then type regsvr32 – u dllname.dll to remove your DLL file from Windows Registry.
Method 2: By Decompiling DLL Files

1. Download and Install the Decompiler
Decompiler is an application that permits you to see the source code used to construct the file or the application. If you want to see the code which makes the DLL file work, you need to use a decompiler to return it to the readable code. Opening a DLL file without Decompiler will result in a jumbled mess of unreadable characters.
• Dotpeek is a free compiler available from jetbrains.com/decompiler/.
2. Open DLL file in Decompiler
When you use dot peen, tap the "File" button and then on the "Open" key and then search for the DLL file you wish to decompile. And then, later, you can explore the contents of the file without affecting your system.
3. Use Assemble Explorer to Browse the nodes of the DLL File.
These files consist of nodes or modules of code that form the complete DLL file. You can then expand each node to see any subnodes that may contain.
4. Double-tap on the node to view the code for it
The code that you select for the node will appear in the right frame of dot peen. You can scroll down the code to review it. Dot peen decompiler will display code in C# or download the additional libraries to view the source code.
• If any node requires the additional libraries to view the dot, peen will attempt to download automatically.
5. Get the clarifications for the various pieces of code
If you had found a piece of code that you don't understand, you could use the Quick Documentation characteristic to see what the command is doing.
• Place the cursor in the piece of code you wish the documentation for in the Code Viewer frame.
• Hit the Ctrl + Q to load the Quick Documentation window.
• Then follow the hyperlinks to learn more about each aspect of the code that you examine.
6. Export the code to the Visual Basic
If you need to manipulate, edit and build up the file on your own, you can then export it into Visual Studio. The exported code will be in the C#, even if it's originally written in various languages.
• Right-click on the DLL file present in the Assembly Explorer.
• Then select the “Export to Project” command.
• Select your export options. You can then have the project opened immediately in Visual Studio if you would like to start it immediately.
7. Edit the code in the Visual Studio
Once you load the Visual Studio project, you will have to complete the control over editing and building the DLL file into your creation.
