It happens that it feels like you’ve been using a computer for a long time, you know all the main programs, even friends sometimes ask you to help you figure out this or that application, like here...

In general, I think you understand a similar feeling when you yourself are faced with some kind of confusion in computer world. I was once stumped by the question of how to open a dll.

And the fact is that at that time I understood little about this issue. I have never seen files with this extension, therefore, as you probably understand, there was no discussion at all about how to open a dll file.

I sat. I figured it out. It worked! I share my experience.

Section 1. How to open dll: definition of concept

As it turns out, files with this extension represent a library. Honestly, if we delve deeper into the etymological meaning, we find out that dll is an abbreviation that can be deciphered as and translated into our native language it means that the file of this format is a truly special library containing various program codes and resources.

What makes it unique? It has the ability to connect dynamically.

Resources for such a file can be anything: images, text materials, audio files, videos, cursors, and many other elements that are used by applications installed on your computer.

But I would like to warn you right away...

Before you set yourself such a task and try to open a dll, think about whether it’s worth doing this at all. Why? After consulting with specialists, I learned that it is possible to view and change files of this kind, but, however, only with the help of a special software. However, this should be done very carefully, because... This may result in complete inoperability of programs using these files.

Section 2. How to open dll. Detailed instructions

Method one. Cygnys Hex Editor

In the computer world there are special programs, called disassemblers, they allow you not only to access, but also to change the code of dll files. A completely logical question arises. Or rather, even two.

1. Where can you find and download such a program? What is it called?
2. Is it possible to do this for free?

I answer both at once. There are a lot of similar applications. Personally, I use the free and very effective version called Cygnys Hex Editor. I liked the latter for several reasons. First of all, thanks to her simple interface, and secondly, because it does not require tedious installation. To download it, you just need to use the direct link on the official website of the manufacturer.

Download and you can use it almost immediately. The information contained in the dll file will open on the computer screen enough in a convenient way. At the same time, both in the form of a table with a set of hexadecimal codes, and in a more familiar display - like text characters. You can read, study and, if necessary, make the necessary changes. Moreover, amendments made to one of the tables will simultaneously automatically change in the second. Convenient, right? There is no need to do any extra work.

Method two. Resource Hacker

You can answer the question of how to open a dll for yourself differently. If you need to view and replace some resources in your dynamic library files, use some specialized program. Personally, I chose the Resource Hacker viewer for myself. With its help, I can not only see and change the code inside the file, but also monitor appearance resource that is created using code. The interface of this program is very simple and understandable even for beginners. It allows you to replace not only the image, but also the audio or video file with your own. Moreover, all this happens not even at the code level, but at more high level objects. This application is also provided free of charge.

- Extension (format) is the characters at the end of the file after the last dot.
- The computer determines the file type by its extension.
- By Windows default does not show file name extensions.
- Some characters cannot be used in the file name and extension.
- Not all formats are related to the same program.
- Below are all the programs that can be used to open the DLL file.

Resource Hacker is free and simple utility, capable of changing, renaming, adding, deleting or extracting executable files, resource files (*.RES) in the operating system Windows shell.

For novice users, everything is very simple. The program is integrated into context menu, which allows you to very quickly compress files located on any disk and in any folder.

How to open a dll file?

What is a DLL?

DLL format files represent a library of dynamic links. They contain program code (there may also be icons). DLL files are needed for Windows operation and COM. You can create DLL files in any programming environment, but this requires programming knowledge. An ordinary user will not be able to edit it correctly, much less create it. If you find such files in system folders– Do not under any circumstances try to remove or change them. This may lead to a malfunction separate program, and the system as a whole.

A DLL file is a small program. You can open all DLL files using one big program for which they were created. A small program, designed as a DLL file, allows you to work, for example, with a printer or scanner. Some DLL files have a “.dll” suffix that is attached to a program when it needs to do something. Sets of DLL files are similar to routine libraries in programming languages.
DLL files have the same conventions as executable files along with code, tables, and resources. The difference can only arise in the interpretation of the fields.

DLL files were first created to effective organization memory and disk space, when using a single instance of a library module. For first versions Microsoft Windows, which had memory limitations - this gave more opportunities.
A little later, DLL files improved development efficiency through modularity. When replacing versions of DLL programs, the system was expanded without affecting the application. It has become possible to use DLL files for various types of applications.
Modularity gradually grew to the concepts of Component Object Model and System Object Model.

But get significant benefits by implementing DLL libraries failed due to DLL hell. It occurs when running several programs of different versions that require completely different libraries. As a result, disruptions began to occur in operating system. In later Microsoft versions Windows now has the ability to use parallel different versions DLL, but the use of modularity has disappeared.

Programs for opening DLL files

1. Resource Tuner

This program will allow you to open and conduct editing DLL file. To do this, click on “Open File”, then select “File” - “Open”. The program has a clear interface and you won’t need much time to learn it.

1. Restorator. Allows you to open and edit DLL files. Using Restorator, you can extract and modify text in DLL files.
2. Resource Hacker. With this program you can very quickly view, change and add content to DLL files.

Hope, this article answered the question: “ How to open a DLL file? But remember - ordinary users you will never need to change these files. If you downloaded a DLL file from the Internet, you may not have installed the program for which it was created. In any case, you should not download DLL files separately.

With the help Resource Tuner you can open executable files such as .EXE, .DLL, .OCX, screensavers (.SCR) and many others. By opening the file, you gain access to the file's resources and can replace icons, cursors, and graphics in various formats, change lines in the menu, dialog boxes and other user interface elements.

However, it is worth keeping in mind that the resources in the executable file are separated from program code, and by changing the program interface, you do not gain access to the program code. Using the resource editor, you can change program controls. The program code cannot be changed using the resource editor.

For more serious changes (which, however, will not lead to anything good without sufficient experience in programming applications for Windows), we recommend using PE Explorer (PE file structure editor) or FlexHex (hex editor for binary files).

Opening an EXE or DLL file in Resource Tuner

Supports multiple ways to open files. To open a file for viewing and editing, click the button Open File on the toolbar or select the command File > Open from the menu. The drop-down menu next to the button on the toolbar gives you quick access to the list of recently opened files. The same list can be obtained with the command File > Recent Files from the program menu. The number of files in the list is configured in the dialog Customize.

You can also open the file with Help Resource Tuner straight from Windows Explorer by clicking on the file right click and selecting Open with Resource Tuner from the context menu.

Or you can simply drag and drop the file icon from Windows Explorer onto the Resource Tuner icon on the desktop or onto the window of the running Resource Tuner.

You can also open the file from the command line.
For example: restuner.exe filename.exe

When opening a file, Resource Tuner produces several automatic operations: unpacks the file if it is detected that it was packed using UPX, then checks the file structure and resources for possible errors, and finally rebuilding the damaged resources in accordance with the format specification executable files.

Errors when opening a file

If an error occurs when opening a file, it is most likely for three reasons: the file is protected, the file is 16-bit, or it is not an executable file at all.

1. Error: The file is damaged, compressed by a packer or protected by a protector.

There is a very good chance that the file has been compressed to reduce its size. There are dozens of packers and protectors for executable files, and new ones appear all the time. Resource Tuner supports unpacking only one, but the most common packer - UPX. Other packers are not supported, and you will have to unpack the file yourself before you can open the file for viewing or editing.

This situation is not considered a program error. We are not going to fight the attempts of other program authors to protect their creations from hacking, nor support the unpacking of several dozen different packagers, including both commercial products and homemade products.

2. Error: The file is defined as 16-bit NE Executable. This format is not supported!

Our programs only work with 32- and 64-bit PE files. The NE format (short for "New Executable") is a 16-bit application format left over from older Windows versions 3.xx. With the advent of Windows 95, this format is considered obsolete and is not used, although it can be executed on modern platforms from Microsoft. We do not support 16-bit files and do not intend to support them.

3. Error: The file is not an EXE or DLL file. At all!

Resource Tuner does not detect a file by extension. If you rename the extension of an executable file, say, correct .EXE to .TXT, or remove the extension altogether, Resource Tuner will not be fooled by this: when opening a file, the program analyzes the file header inside the file, and does not look at the extension at all.

Therefore, if Resource Tuner tells you that the file is not executable, then it is so. If someone supplied for some reason text file in the game delivery with the extension .DLL, then this does not stop the file from being text and does not become dynamic library. Don't be fooled by the file extension.

Which files do not make sense to open in the resource editor?

Although Resource Tuner is designed to open and edit any 32/64-bit executable files, there are some types EXE files, in which there are practically no resources.

1. Files created by Visual help Basic.

In such files, there is nothing in the resources section except an icon and version information. Lines and dialogue in programs written in Visual BASIC are stored in their own proprietary format, and they do not use the standard resource section.

2. EXE files of gigabytes or more in size.

Since Resource Tuner is a 32-bit program, there are natural restrictions on placing the image of the file being opened in virtual memory within the first gigabyte. A file of a gigabyte or more in size simply will not fit there.

3. Self-extracting archives in the form of EXE files.

In such files, there is nothing in the resources except an icon and version information, and maybe even that. Essentially, this is archived data equipped with a subroutine for unpacking.

4. Installers of other programs.

In such files, there is nothing in the resources except an icon and version information. Very similar to point 3. An installer file can be thought of as a container that contains another .EXE file in compressed form and a routine to extract it. In addition, programs for creating installers use different algorithms to store archived data within themselves.
