How do I determine which are the system files on the C drive?

The steps are as follows:

1. Open a folder window and find the "Tools" button.

2. Select "Folder Options".

3. Click "View".

4. Check "Hide Protected System Files" to confirm.

5. In this way, the system files will be hidden, and the others are the other software installed. That is, you can selectively delete it.

Find the windows folder and see when it was created, it was created at the same time as it is the same system folder. I'm really with the little genius. All systematic stuff should be built at the same time.

Different operating systems use different file systems.

Take Windows operating system as an example: Windows 98 uses the FAT32 file format, which can support the FAT16 format, and Windows XP can use either the NTFS format or the FAT32 format, but the NTFS file system is generally used. Windows 7 also uses the NTFS file system.

An operating system (OS) is a computer program that manages the hardware and software resources of a computer. The operating system handles basic tasks such as managing and configuring memory, prioritizing the supply and demand of system resources, controlling input and output devices, operating the network, and managing the file system. The operating system also provides an interface for users to interact with the system.

The C drive is the system disk, and the windows inside is the system folder, and deleting files may affect the stability of the system, so this folder will never be moved.

Program files (or program files (x86)) are folders used to install programs, which is a variety of software running files that can be deleted, but it is not recommended to operate directly on disk, directly manipulating c disk may be because I don't know the specific role of the file to delete the software by mistake and the software does not function properly.

How to clean up the C drive:

1.Select diskc, right-click, and select Properties.

2.In the pop-up window, select "Disk Cleanup", and you can see the progress bar for calculating the cleanable space. Wait a while.

3.When the scan is complete, select the files you want to delete in the pop-up window and click OK to delete. (The files scanned here are all files that can be cleaned and can be safely deleted).

4.After deletion, you can also select "Compress Drive" in "Properties" to save C drive space.

5.If the space on the C drive is still small after the above steps are completed, clean up the C drive by changing the installation location of some software: click "Start" at the bottom left and select "Control Panel".

6.Click on the Control Panel to open the Uninstaller.

7.After entering the uninstaller, you will find some unusual software in it, click on it and select "Uninstall". (Games like LOL and some drawing software take up a lot of memory, these software should not be installed under the C drive, if you have installed it but don't want to delete it, you can move them to other disks.)

The second and third ones are loaded with software.

Hello mainly as follows, these files can not be deleted or transferred, I helped you mark them with red arrows, these are system files.

Method 1: Determine by the disk icon.

1. Win7 Win8 Win10 system drive letter has a windows flag icon;

2. Open "Computer" and find the drive letter with an icon, which is the operating system installation location.

Method 2: Determine the value based on disk management.

1. Right-click "Computer" or "My Computer" on the desktop and select "Manage".

2. Open computer management, click "Disk Management", check the "Status" column of the disk, there is "System" or "Startup", which means the system installation disk;

3. If "Boot" and "System" are in different drive letters, then the C drive containing "Boot" is the system installation location, and the "System Keep" partition is part of the C drive.
