What should I do if the C drive becomes smaller and smaller?

You can install a super rabbit software, use its function of cleaning the registry and cleaning up the junk files on the hard disk, clean up the C drive, remove unnecessary files and trash bins, and make space.

Then use VOPT software (Quick Defragmentation Disk Utility) to organize the C drive, organize the fragmented files, and increase the free space of the C drive.

Prevention: You can install some programs such as games on the E drive, applications on the D drive, etc., and install the applications by category, but not in the C drive, saving the space of the C drive.

If the space of the C drive is too small, it will affect the size of the available virtual memory of the system, which will affect the stability of the system, so it is necessary to delete unnecessary C drive files in time and organize the C drive (once every two to three months).

I've also been in this situation, you can turn off hibernation in the power options and turn off system restore in the system properties. These two functions take up too much space on the C drive, and a few Gs can be freed up when turned off.

The landlords mentioned above can try it.

I don't know if you have installed "Rising Antivirus" software? If you install it, then your problem may lie in the settings, its default setting is "hard disk backup once a day", you can change to no backup. I've had this kind of problem on the planes of many of my friends.

If you don't have Rising antivirus installed, it may be because you save the file according to its default path, generally the default path is the C drive, so that the free space of the C drive is less and less, you can move some files to other disks.

Changing to a big hard drive will definitely solve the problem.

Could it be that you used the default path to install the program when installing the program?,I see a lot of people who are new to the computer do this.。 It could also be a virus. It is recommended to use Disk Cleanup to delete the files restored by the system, which can free up some space, uninstall the files installed in the C drive, and reinstall them in other disks.

Delete the temporary files and clean them up.

Look at what file takes up too much space, be sure to pay attention to this kind of file, I have seen this file have 2G so big. This type of file is generally hidden.

I think the system you are currently using must be XP, if the system restore function of the XP system is turned on, then your C drive will be smaller and smaller, you can right-click on "My Computer" on "Properties", and then open the "System Restore" tab, and then turn off "System Restore".

Use a D drive or an E drive to store the data, and then select the path when installing the program.
