As a geek editor and company IT, I often solve many difficult problems on the computer, and in the process of many practices, I found that many friends' computers have a common problem - the C disk rings the red warning.

In this case, no matter how high your computer is configured, or how fast the hard disk is, it is easy to run slowly, stutter and crash.
This issue of geeks recommends that we provide you with several "save C disk" solutions, take advantage of the May Day home rest, and do a big cleaning of your computer.
PS: The most effective method is at the end.
C disk does not sweep, why sweep the world
When the C drive is full, you should first clean up the junk files in the system, which not only includes the useless software cache, but also the files retained after the system upgrade and the useless installation package after downloading.
As for the cleaning software, many friends may use the cleaning function of XX Computer Manager, and some people will choose CCleaner, which has a good reputation in foreign countries.
However, after I used it, I found that in order to clean up the garbage, it seems that it is not necessary to install a computer housekeeper, and the foreign software is actually not suitable for the Chinese computer software environment, so we share a single-file version of the domestic cleaning software here.
Kingsoft poison bully garbage cleanup
As you can see, we provide junk cleaner software extracted from Kingsoft, which does not need to be installed after downloading, and is ready to use.
In addition to cleaning up system junk, the software's best thing is the ability to clean up third-party software, which supports scanning and cleaning of 469 commonly used software, 80 browsers, 54 social software, 139 audio and video software, and 236 games.
This covers almost all the software in China, which is difficult to compare with the cleaning software abroad.
It also offers a deep cleaning feature that cleans up various software downloaded files, infrequently used files, uninstalled software residue, useless plugins, and more.
Clear Legacy Forces (Windows Update Files)
If your PC has been updated with a major version of Windows, you're likely to leave a backup file of your older system. Open your C drive, if there is a "Windows.old" folder in the root directory, it means that there is a residual system backup.
This folder has a very large footprint, such as 22.5 GB on my C drive, and its role is to use it as a backup to fall back when a new system has a problem.
However, in my many years of experience, the new system will basically not have problems, so it is recommended that you clean it up directly.
If you're using a Windows 10 system, here's how you can clean it up:
Open "This Computer", right-click on the C drive, select "Properties" - "Disk Cleanup" in turn, and wait for the system to automatically scan.
After the system scan is complete, you need to perform a deeper scan, click "Clean System Files", at this time you need to wait for a while until the scan is complete.
Then find and check "Previous Windows Installation Files" in "Files to Delete", click "OK", and the cleanup is complete.
If you're using the latest version of Windows 11, the approach is a little different:
Open "This Computer", right-click on the C drive, and select "Properties" - "Details".
In the new pop-up settings menu, wait for the load to complete, then select Temporary Files
After entering the "Temporary File", continue to wait for the loading to complete, and then the "Previous Windows Installation File" will appear, check it to delete it.
WeChat professional cleanup
No matter which platform, WeChat occupies a huge amount of storage space, if you use the PC version of WeChat for many years but never clean up, then it is likely to have occupied dozens of GB of space, many of which are useless memes, meaningless pictures, videos and so on in group chats.
In order to solve this problem, some individual developers have launched WeChat-specific cleaning gadgets, and we also share one here.
Clean My PC Wechat
After opening the software, you need to click "Settings" to create a configuration file, and then you can read the WeChat file.
In the settings screen, you first need to check "Whether to clean up this account".
Then you can choose to clean up the pictures, the files you receive, the videos (video files and video covers), and the image cache (from the Mini Program, the official account, etc.).
Then go ahead and choose how long ago you clean up your files.
Finally, don't forget to click "Save".
Back on the main interface, click Start to clean up. After the cleanup is complete, if you regret it, you can also pick up the garbage in the Recycle Bin.
WeChat record transfer
If you feel that your chat history is very important, but you don't want to take up C disk space, then you can follow the following methods to transfer WeChat chat history to other disks.
Start by opening Settings in WeChat.
Then in Settings, open File Management and click Change.
Then you can transfer the WeChat folder to another disk (you can create a new folder in another disk).
Then click Restart WeChat, you will start to automatically transfer files, after the transfer is completed, start WeChat again successfully.
C drive expansion, fundamentally solve the problem
To solve the lack of C disk space, the more effective way is actually to make the C disk larger, many people's C disk has been almost full, but the D disk, E disk... There's also a lot of space. If you have a similar situation, then you can divide the space of other disks to the C disk to achieve common prosperity.
But when it comes to disk expansion partitioning and the like, many friends will feel that there are hundreds of millions of points of complexity, we provide a seemingly professional, in fact, everyone can learn the method, the most important thing is that this method will not destroy any files and data.
DiskGenius expansion dafa
First, a powerful tool is needed – DiskGenuis
Once we open the software, we first select the C drive.
Then in the upper "Partition" menu, select "Resize Partition".
Then the software will ask us to choose the disk that is being exploited, I have the F disk here, usually everyone's computer should be a D disk.
After selecting it, click OK to enter the next interface.
By default, the software divides the exploited disk into two copies, and then divides one to the C drive, of course, you can also adjust it yourself.
For example, at present, my C drive is 171.9 GB, and I want him to get to 200 GB, so I only need to give the C drive 28.1 GB, which is enough, so that the F drive will not be very uncomfortable.
Here's how, we can fill in 28.1 in the "space in front of the partition" (it may take a few seconds to appear after filling in).
Immediately after that, we click "Start", and then the software will pop up an important prompt, and after confirming, click "Yes".
Then the software will automatically operate, then the computer will automatically restart, and will automatically enter the maintenance system, waiting for the operation to be completed after the computer will restart again, after a meal of operation, turn on the C disk expansion again to complete.
For C drive cleaning and computer optimization, if you have other experience, you are welcome to discuss and share with you, or if you have any problems, you can also leave us a message through the background.
