What are the six Windows 10 default folders that should not be touched? I believe many inexperienced people are at a loss about this. Therefore, this article summarizes the causes and solutions of the problem. Through this article, I hope you can solve this problem.

In addition to your personal files and folders, the computer also contains a lot of data created by Windows itself, which takes up a lot of space. With a little effort and search, you will find a sufficient number of temporary files that do not affect the performance of the system.

However, you should not change other files and folders unless absolutely necessary. Deleting this data can lead to system instability, file loss, and other unforeseen consequences. Here are six default Windows 10 folders that you should never touch. Be sure to pay attention.

1. Program Files and Program Files (x86)

Location: C:\ Program Files, C:\ Program Files (x86)

Whenever you install an application by running the setup.exe file, the installer creates a directory in the Program Files folder, adds values to the registry, and performs other necessary tasks to make it work properly. Therefore, if you look at the Program Files folder, you will find the directory of most programs installed on your computer.

Except in rare cases, do not touch the program data in these directories. They contain the configuration information needed for the program to run. If something is changed, the integrity of the file may be compromised, which will result in the need to reinstall the application.

If you want to uninstall the program correctly, you should use the applications and Features of the Settings menu. It only deletes the application directory from the Program Files folder, does not delete other links to that application directory from the system, and does not delete other directories and the remaining files in the registry.

If you are using a 32-bit version of Windows, only 32-bit applications can be installed, and there is only one Program Files folder on disk. There is another Program Files (x86) folder on the 64-bit version of Windows. It installs 32-bit programs, while 64-bit programs are stored in the regular Program Files folder.

2 、 System32

Location: C:\ Windows\ System32

Almost all system data is stored in the C:\ Windows\ folder, but the System32 directory deserves special attention. It contains hundreds of DLL files as well as many programs that are critical to the proper operation of the system.

For example, you can find services responsible for sound manipulation on your computer, files needed to correctly boot Windows, resources responsible for displaying fonts correctly, and so on. This folder also contains executables for standard Windows programs. For example, calc.exe allows you to start your calculator, while cmd.exe allows you to start the Windows command line.

Obviously, because this folder is critical to Windows operations, reckless changes to the files in it can paralyze the entire system.

3. Paging file

Location: C:\ pagefile.sys

The internal memory of the computer is responsible for temporarily storing data for all running applications. For example, when you open Word, the program itself and the necessary data will be placed in memory. This is why there is a lot of memory that allows you to easily work in many programs at the same time.

If the physical memory is full, Windows will start using the page file. This is a dedicated part of the disk that acts like memory. If your computer has enough memory installed, you are unlikely to see how the page file size increases. However, using this file degrades the performance of the device because internal storage is slower than memory.

If you check the size of this file, you may see several GB sizes. Of course, you can disable the use of paging files to free up space, but this is not a good idea. There are no paging files, and when memory fills up, programs may stop running because they cannot access extra memory.

Windows allows you to manage virtual memory manually as needed, but most users should allow the operating system to do so on its own. If you have problems using a small amount of memory, the best solution is to buy a memory stick and add it.

4. System Volume Information (system volume information)

Location: C:\ System Volume Information

Another large folder (the purpose is not obvious) is the system volume information. In fact, it contains some files that are needed for the proper operation of the Windows function. In most cases, when you try to open this directory, Windows will only display a warning: "access denied".

This directory contains backup files and system restore points that can be used to roll back unwanted changes to the system. Of course, you can reduce the size of this folder or turn off system restore completely. To do this, search for create restore Point in the search box on the taskbar, and then press Enter. In the window that appears, click the configure button, and then specify the parameters you want.

In addition to the system restore point, the system Volume Information directory also contains file index data. Without them, the search in the system may be very slow. In addition, this folder is used for the Volume Shadow copy service, which is responsible for backup.

Like other important folders, you should not change the contents of this folder. Do not try to force access to delete files-Windows requires this data to function properly, and there is no reason for the average user to change it.

5 、 WinSxS

Location: C:\ Windows\ WinSxS

The WinSxS folder represents Windows Side By Side (side by side) and was created to solve compatibility issues with different versions of Windows. The colloquial term DLL Hell (Hell DLL) is the best language when conflict, repetition or interruption occurs in dynamically connected dll (dll).

To solve these problems, Microsoft began to use the WinSxS folder to collect multiple versions of many DLL and download them on demand when needed to run specific programs. For example, this can improve compatibility when a program needs to access an outdated version of DLL that Windows no longer contains.

The longer you use Windows, the larger this folder becomes. As you may have guessed, deleting the files in this directory is a bad idea. Instead of modifying the files directly, you should use the disk cleanup tool or the "system-Storage" section of the system settings.

6 、 D3DSCache

Location: C:\ Users\ [user name]\ AppData\ Local

The last folder introduced is not as important to operating system tasks as the other directories above, but many users may still be confused about its purpose. D3DSCache is a directory that contains cache information for Microsoft Direct3D API.

It is part of DirectX and is used to display graphics in games and other applications. In general, files in this folder should not be modified, especially because they take up only a few megabytes. However, if you encounter problems in the game, clearing this cache may be a good solution. However, don't delete files blindly.

Important: do not directly modify or delete files in the system folder

Windows hides a lot of folders, and for many reasons. There is no reason for the average user to modify the contents of these directories directly, because Windows provides a variety of tools to manage these files without directly harming the system.

If you find a strange hidden folder on your computer, please don't delete it in a hurry. First, find information about it on Internet so as not to damage the performance of your computer. In addition, don't forget to back up regularly so that you can recover lost data if problems occur.
