Open DLL File Extension: How to open it?

What is DLL File?

DLL stands for Dynamic Link Library. It is a library that includes the code and the data, which can use by several applications simultaneously. For example, in Windows OS, the Comdlg32 DLL will be executed as the common dialog box related to the functions. Thus, every single application uses the functionality which is included in the DLL to implement an Open Dialog Box. DLL file also helps to promote code reuse and the efficiency memory usage.

Using a DLL file, an application can get modularized into separate components. For instance, an accounting program gets sold by the module where every single module can get loaded in the main program at run time if that particular module gets downloaded in the system. As all modules are separate, the loading time of the application becomes faster. And the module will get loaded only if the functionality of it will request.

In addition, updates become easier to apply to each module without affecting the other parts of the application. For example, if you have a payroll program, the tax rates change each year. When these modifications get inaccessible to the DLL file, user can then apply an update without any requirement to build or download the complete program again.

Steps to Open DLL File

To open DLL File, you need to follow these defined basic steps, and that’s it your work gets done.

Step 1: Establish the use of DLL Files

These files generally run in the background while using Windows applications. Each DLL File often has numerous functions which they can execute that the programs can access to perform those functions. Some of the functions that DLL files contain:

  • Drawing Graphics
  • Managing Fonts
  • Displaying Text
  • Making Calculations

Step 2: Search for an appropriate program that opens the DLL file and follow these steps.

Some programs are available to open the DLL files. Windows computers already have an existing registry application where you can register your DLL files. Visual Studio or Decompiled are the two programs that should get downloaded to read the DLL file extension. In contrast, Visual Studio online will let you look at the DLL without downloading or searching the program. To describe this process of opening DLL files in detail, you can follow these four methods to open DLL Files


Microsoft Windows 7 and Fresh Registry

Some steps listed below that can help you to open the DLL file on Microsoft Windows 7 computers and the new one:

  • Open the Prompt Command: open the Prompt command by clicking on the Windows Start Menu or simply holding the Windows Key+R and typing “cmd” in the prompt bar, which displays on the screen.
  • Open Folder holding the DLL file: once you get the folder, hold Shift Key and then right-click on the folder to open the prompt command directly in that folder.
  • Type “regsvr32 [DLL name]. dll” and hit Enter Key: This command adds on the DLL file into your Windows Registry, that helps you to access the DLL file. You can also use this function to add the new DLL files to your system.
  • Type “regsvr32-u [DLL name].dll” and hit Enter: This function will remove the DLL file from the registry. Users can also use this function to remove the DLL files that do not behave properly.

Microsoft Windows Visual Studio

It is a program that permits you to view, edit and build the code into a DLL file. When you import the code into Visual Studio, it will automatically convert it into the programming language C# even if it gets written in another programming language earlier.

  • Install Microsoft Visual Studio: Before downloading the program, ensure that your system meets the requirements to run that program. After confirming this then only install the program in your system.
  • Open the folder that contains the DLL file and click on the “Export to Project” button: To view the code and find something that requires any change, you can use another program. While in another application, you can right-click on the DLL file to get it export to the Visual Studio. It would take the DLL file from the application you are using and move it into the Visual Studio.
  • Edit code: Using Visual Studio, you can edit the code to run the functions you need. Visual Studio can also use to read the DLL file without editing the code.

Visual Studio Online

It is a method that you can use if your system does not have the Windows Visual Studio installed. Look at the steps below to open the DLL file using Visual Studio Online Version:

  • Open Web Browser: As we all are already aware and pretty much familiar with the web browsers to date, it has become very convenient to reach Online Visual Studio.
  • Enter Web Address for Visual Studio: Search the term “Visual Studio Online.”
  • Login or Create New Account: You may require a registered Microsoft account to use online visual Studio. If you already have a Microsoft account before, you can log in or Sign In. If you don’t have an account earlier, then create a new account by clicking on “Create an Account.”
  • Upload DLL File: Once you reach online Visual Studio, you will find the DLL file in the File Explorer and then upload it into the application to read and edit it.

Decompiler Application

Another method to open the DLL file is by using the Decompiler. It is a program used designed to take the functional code and then create a usable file that can adjust the code and redesign it as the functional code. Decompiler is the safe option as with Decompiler, you can look at the code without changing it, and it won’t affect your system.

  • Search Decompiler and Install it: Among the few Decompiler choices, select the one you feel is the most suitable and comfortable for your system.
  • Open DLL files in Decompiler: This stage varies from different programs, but still, you will surely find the button named “File” that can open the list of all DLL files you require.
  • Use Assembly Explorer to search the DLL file: DLL files save the information as the “Nodes” and “Sub nodes” that can explore in a decompiler. Thus, by clicking on a single node, you can see all the subnodes included within it.
  • Double-tap the node to read the code within it: when you view the code, you can scroll throughout to review and ensure the different aspects will execute the functions you require. Protection Status Visit File Transit
