5 Windows Folders and Files You Should Never Delete

You may be deleting unnecessary files and folders frequently to free up space on your hard drive. But if you don’t want your Windows to crash or programs to become inoperable, don’t delete these 5 files or folders. As Now You Tech, we will talk about them in this article.

Windows Files and Folders You Should Not Delete:

  • Program Files and Program Files (x86) Folders
  • System32 Folder
  • Swap File (Pagefile. sys)
  • System Volume Information Folder
  • WinSxS Folder

Your hard disk may be full. In such a situation, it is natural to try to free up space by deleting files and folders. You can even learn how to clean unnecessary Windows folders with a little research.

But there are some Windows files and folders that you should definitely not delete or even touch. Deleting these folders or trying to move them to another location can either render some programs inoperable or worse, crash Windows completely.

In this article, we share with you 5 Windows files and folders that you do not even need to pass near and that you still think of deleting somehow, but you should definitely not touch. Remember; You should never delete the files or folders you will see below…

Program Files and Program Files (x86) Folders

When you install any program, the installer adds its entries under the Program Files folder, creates some records in the registry, and performs the necessary tasks for it to run. Therefore, when you look in the Program Files folder, you will see the installed programs.

You don’t need to touch the program data, which is mostly located in this folder. If you play with the files of any program here, you will likely find that the program is no longer running. In this case, you may need to reload the application.

If you want to uninstall a program, you must use the Programs and Functions icon in the Setting options. This method is not a good removal method, as deleting the program folder will not delete other entries created by the program on your system.

System32 Folder

Actually, we can include everything under the C: \ Windows folder in this list, but the System32 folder is even more important. This folder, which stores hundreds of DLL files, is critical to the proper functioning of your computer.

You will usually have nothing to do with the System32 folder, but this can sometimes be the subject of internet jokes. Some users say that System32 to have fun with new users is a virus and they can speed up the computer by deleting the folder. However, since this folder is indispensable for Windows, deleting the folder might force you to reinstall Windows.

Swap File (Pagefile.sys)

When your physical RAM is full, Windows uses the file named paging file or swap file. This file on your hard disk is used as RAM but is much slower than real RAM.

Open Settings to change the size or location of the swap file; Type “Advanced System Settings” in the search box. In the new window that opens, go to the Advanced tab. Here, click the Settings button in the Performance section and select the Advanced tab in the window that opens. You can access the relevant section with the Set button in the Virtual Memory section. We recommend that you leave this setting on automatic settings. If you think you have insufficient RAM, the real solution is to add RAM to your system.

System Volume Information File

At first glance, it is not easy to understand what this folder is for, which can easily exceed a few GB in size. Windows even gives an access error when you make this folder visible and click on it.

This folder contains restore points that allow you to restore when your system crashes or a problem occurs that you cannot fix. To reduce the size of this folder, open the Start Menu and type Advanced system settings, and click on the result. Click the “System Protection” tab in the window that opens. Select the C: drive and click the Configure button. Here you will be able to choose the space reserved for restore points. Note that if you shrink the area, the number of restore points will decrease.

It should also be noted that the System Volume Information folder stores data for fast searching on your drives.

As with the other folders we have listed, do not try to make changes in this folder for Windows to work properly.

WinSxS Folder

WinSxS, which is short for “Windows Side By Side”, was created to fix a problem with DLL files in Windows 9x versions. This issue is resolved with the WinSxS folder containing different versions of DLL files. This ensures compatibility when a program wants to access an older version of a DLL.

This folder can grow as you use Windows. However, as you can imagine, it would not be a good idea to select and delete the file from this folder. Don’t mess with this folder for cleaning, instead use the Disk Cleanup tool to delete unnecessary files.
