What is a .dll file?

They are a type of libraries containing code and data that can be used by more than one program at the same time. Dynamic-link library (DLL) files introduce the concept of shared library on Windows.

Any program on our computer can use a functionality contained in a DLL to implement a dialog box. It helps to promote code reuse and more efficient use of memory. A very good example would be the Comdlg32.dll file that performs common functions related to dialog boxes.

This file type offers a number of advantages to developers. The strengths of this file type are:

• Use of fewer resources: A DLL can be generated that is used by several programs. This avoids duplication of code and thus saves space on the hard disk and RAM. In addition, they have an impact on the performance of programs running in the foreground and background.
• Modular architecture: Promotes the creation of modular software. Helps developers save time and costs. Indeed, it is easier to use existing elements than to create a program from scratch.
• Ease of implementation and installation: Upgrades or fixes, implementations and installations do not require new linking to the software. In addition, since sharing is allowed, the update benefits all software that uses the .dll.

Not all good news

While they have many advantages, this type of .dll file is not without its problems. It is not uncommon for one of these files to generate issues and prevent a program from running. The difficulties with these files, years ago, were very problematic for games, although they have improved.

Nevertheless, they have these problems:

• Errors: Some executables require some .dll files to be available at the time of execution. When the file is not found, a rather flashy error appears, indicating that it failed to start because of this issue.
• Exploits: .dll injections with malicious code are quite common in Windows applications. A malicious actor can change a good .dll to one that is infected. It is required to know which .dll will be called by the operating system and then change it to an infected one.
• Speed: A dynamic linking process is slower than a static linking process. They require more CPU computation cycles. But this is a one-off, as most of the time it does not need resources.

How to solve a problem with a .dll file?

There is the DLL Universal Problem Solver (DUPS) tool that allows auditing, purchasing, documenting and displaying DLL information. Let’s take a look at the tools on which DUPS is based:

• Dlister.exe: Generates a list of all .dll files on the computer and records the information in a file or text file.
• dcomp.exe: Compares two or more text files and produces a third file and generates a third file with the differences.
• Dtxt2DB.exe: Allows the loading of b-generator text files into the dllHell database.
• DlgDtxt2EB: Provides a GUI support for .dll files.

Conclusion

They are a necessary file type that allows to reduce the load, mainly in games. The truth is that it is used for many other applications, although the best known is gaming. It saves resources, but it is also quite common for this type of file to generate a lot of problems.

How to delete DLL files with DLL Archive

As mentioned, it is possible to delete DLL files. This can be done manually. However, the user runs the risk of disabling the system. For this reason, today we will use a tool that allows you to select the files that are no longer needed. This application is DLL Archive and you can download it for free from this link. Then run it like any other Windows program. What this tool does is locate the DLL files on your computer. It then determines which ones are not needed and extracts them into a folder. Well, the first thing you must do is click on Configuration.

Then, enable the Only display 0-hits option. You must set it to Enabled

Now, start the DLL file search with the Search button.

Please wait while the hard disk scan is finished. After a few minutes, the wizard will display a list of orphaned files. Please note that the files have to show 0 in the hits section. After verification, please click on Archive all. This will cause the files to be hosted at the following address:

C:\Windows\DLLArchive

After having all the DLL files isolated, it is time to restart the computer. Then check that the system is working properly. If so, then the removal of DLL libraries has been completed successfully. In that case, it is enough to delete the contents of the folder mentioned above. On the contrary, if any error persists, please check the text file filelist.txt to consult the original path of each DLL. And consequently, you will be able to restore them if necessary.

Conclusion

Thus, we have seen how to delete DLL files in Windows 10. This is very interesting since lightening the system is always welcome. All right, this is all for the moment. Before saying goodbye, I invite you to see our post about how to install MinGW on Windows 10.
