Open DLL File

What are DLL Files

File extension dll stands for Dynamic-Link Library. These contain codes that are used by different applications. The codes in these can be edited by the user without changing the whole program or application.

They can also be used in the form of plug-ins. Which are extended features that can be downloaded or purchased.

When different applications or programs have to do the same tasks at one time then that particular action or task is placed into a .dll file which makes it easy to be used by different programs.

This can be a benefit as it saves memory.  They are automatically provided by Windows and allow different programs or functions.

Normally these are not to be opened due to them being sensitive as they can cause errors. Editing them or deleting them can lead to errors and many programs not being performed. There are some programs that open this format:

  • Microsoft Visual Studio 2017.
  • Microsoft Visual FoxPro.
  • Resource Hacker.
  • Client.

These can be opened with special software and with updated functions. It can be opened and read by the user. It holds multiple codes and functions or actions in one.


Open dll file

You can always use the old school double-click method. If it does not open then it means that a proper software for opening up dynamic link library files is not installed in your PC.

If it is not opening these then it can also mean that your PC is not reading those correctly and is using the wrong software to run them.

Sometimes opening .dll is not the best option and letting them remain untouched is better. As some of this format contain Trojans in them which can make your computer infected or damage to your whole system.



One of the methods according to Wiki How can be:

  1. Download and install a compiler.
  2. Open the .DLL in the compiler.
  3. Use the Assembly Explorer to browse the nodes.
  4. Double-click a node to view its code.
  5. Export the project to Visual Basic to edit the code.
  6. Edit the code in Visual Studio.

They are very important as it can be said because they save memory and help all the programs while working in the background. They help several parts of the programs to perform actions or procedures of the same type.



They are not to be opened by the normal user because if they are modified or played with then they can cause lot errors in the functioning of certain programs which can also lead to crashing of applications.

There is not any specific way to open a dynamic link library file but if you want to edit or if someone sends it to you through mail then you can use the different programs that were mentioned above.

Messing or editing it can actually lead to severe damage which means it is safe not to open them.
