How Many Types of DLL Files Are There?

DLL files are libraries used by multiple software applications. There are many types of DLL files. Here are a few. Read-only, Non-executable, Section, and Executable. These files vary in size and use. So, if you want to download and use DLL files, you should know how many different types of DLL files exist. There are over a thousand types, but we’ll focus on a few of the most common.


There are three ways to access the sections of a DLL file. Each team can have multiple names depending on how the DLL is organized. These names are called virtual addresses and refer to the location of the file’s memory. Those addresses are then placed in the section data by the loader when the file is loaded. For more information, see the Sections of the DLL files article. Let’s begin with the first type of section.

The first type of section contains the data directory. This directory is essentially an IMAGE_DATA_DIRECTORY structure. Each entry specifies a section’s size and location relative to its header. It also includes the section header, which sets the exact location of the file’s offset. This information is necessary for the application to know where to find the data. Sections can contain multiple data directories and data files.

Another type of section is the private section. A single process typically uses this section. This process has its copy of the data in the DLL file. Sometimes, however, data is shared. In this case, two or more methods can share the data. In this case, one process’s data may be corrupted by another, affecting other operations sharing it. This is particularly important for guest processes, as they can potentially corrupt a privileged process.


DLL is a short form of dynamic link library. DLL files are dynamically linked to applications and do not have the primary function. They use the memory space of the application to execute. Contrastingly, executable files, or EXEs, have the introductory part and can run independently. This article will discuss the differences between executable and non-executable DLL files.

The difference between executable and non-executable files is that executable files are directly executed by the CPU, whereas the CPU does not directly execute non-executable DLL files. While executable files contain code that can alter your computer’s resources, non-executable files do not. Luckily, there are ways to identify non-executable files and avoid the potential for damage.

The simplest way to distinguish an executable from a non-executable DLL is to examine the type of executable code inside. Non-executable files, for example, are made up of code that the CPU cannot execute. A third party, such as a program vendor, often provides these files. They are typically offered with Developed Software.


A read-only file cannot be edited. To make this change, open the file and right-click on it. Then, click Properties. Uncheck Read-Only and check Archive. Then, restart your computer. The changes will now be visible. You can try making a new file. You can cancel the difference and return to the original file if this option does not work. You can even use a third-party tool that allows you to edit the file.

Another option is to copy the file. DLL files are a vital component of many computer programs. When a DLL is missing, you will encounter an error message. This message will tell you which programs are affected. You can try running Windows repair if this does not solve the problem. The repair will fix the program and return your computer to average speed. If the error persists, you can perform Windows recovery to restore your computer system.


DLL files are separated into two categories. The first category is executable, while the second category is read-only. DLLs are split into two sections: executable and non-executable. The executable section contains code, while the non-executable section contains data. Unlike EXE files, DLLs do not execute directly. But the same data can be used to load and run programs.
