Causes and solutions for Windows System Disk Space exceeding the actual size

I. Question raised: when I got up this morning, I found that my computer's c disk space was significantly reduced. At first, I thought it was because my computer has not been shut down recently, and there were too many temporary files and caches. However, after using tools such as Windows master to clean up or perform disk cleanup, it is found that the system disk status is still not good. I had to go to the Internet to find information. My computer system disk has been sorted out, so I had to use pictures provided by other students on the Internet to illustrate my problem.
First, you can see in my computer:
However, in this disk, select all the files and folders (including hidden files and folders) and the result is:

Note: The first figure shows that the available disk space is 56 GB, and the total space is 80 GB. Therefore, the used disk space is 24 GB. The second figure shows: the disk space used is 14 GB. The difference between the two is obviously 10 Gb. Where is the space of the 10 Gb? This article will analyze the possible locations and solutions for the 10 Gb space. Ii. solution:
Based on the information provided on the Internet, I will sort out the following four possible causes and corresponding solutions.
First, the record tool provided by the system keeps the cached files or images when the disk fails or exits halfway. Type 2: automatic backup in Windows. However, Windows automatic backup is usually disabled by default. You can view and set the backup space in the following ways: right-click computer> Properties> advanced system Settings> system protection> configuration.

Third: Windows Virtual Memory Page (pagefile. sys) space occupied by the system disk; Description: Pagefile. the sys file is designed by Microsoft for the Windows system and is mainly used to configure a virtual memory space for the computer. When the computer's memory (RAM) is insufficient, you can create a virtual memory capacity on the hard disk to make up for the inherent physical insufficiency and improve the computer and the running performance from the page. You can set the size of the virtual memory and the location of the hard disk to be stored. Specific Practices: right-click "computer"-> "properties"-> "Advanced System settings"-> "advanced"-> select "Settings" for "performance"-> "advanced"-> "Change "Authorization + authorization + 9PDtcTAy7fRtcS/1 bzkoaMKPGJyPgq/authorization + authorization/authorization + z + authorization + tppqocno1spoqstatoa1xdcwjarjcjxpbwcgc3jjpq =" http://www.2cto.com/uploadfile/Collfiles/20140217/2014021709143423.jpg "alt = "\"

Note: by default, this percentage is 75%, which is the balance value adopted by the Windows development team after evaluating the computer, if Hiberfil. if the sys File is too small, the system will not be able to sleep. If it is too large, it will waste disk space. If the following fault code is displayed on the blue screen during sleep, it indicates that the Hiberfil. sys file is too small and must be reset: STOP: 0x000000A0 INTERNAL_POWER_ERROR parameter 1 parameter 2 parameter 3
(Parameter 1 is always 0x0000000B, parameter 2 is the number of bytes in Hiberfil. sys size, and parameter 3 is the number of remaining memory data bytes that cannot be compressed and written to Hiberfil. sys)
2) disable the system sleep function. Hiberfil. sys will also be automatically deleted to release the system disk space. Execute the command: powercfg-h off
3) Enable the sleep function and run the command powercfg-h onhtmlhttp: // rewrite/
