Drive C fills up on its own in Windows 10

If your C drive fills up for no reason, may be due to a malware attack, file system corruption, etc. Drive C is generally taken as the system partition in a computer system. The system volume is the partition where Windows is installed and where all third-party programs should be installed by default. Having some free space on the C drive is essential, as it is often needed during a Windows update or upgrade.

However, in some cases, drive C fills up on its own, what can be really awful. Some users have reported that when they check the drive properties, shows drive is full. However, when they open the drive and select all the folders, size is only part. Therefore, we are here to help you with this problem.

What causes drive C to fill up on its own in Windows 10?

Since drive C is primarily the system volume, the disappearance of free space may be due to the following factors:

• Malware attack . If your system is affected or under the control of malware, can make free space disappear on system volume.
• Corrupt system files . Damage or corruption of your system files can also contribute to the disappearance of free space.
• System restore points . Sometimes, machines are configured to use more than enough space that is required for a system restore point that can cause the problem.

We have rescued some effective solutions that you can implement to solve your problem. Make sure to check all of them if the problem persists.

Solution 1: scan your system

Starting with the most general cause, you should run a full system scan with Windows Defender or any other third party antivirus to detect any malware that is present on your system. If you have disabled Windows Defender without having a third-party antivirus on your system, certain malware can easily damage your system, as it is fully open. Therefore, make sure you always have Windows Defender on, except when you interrupt a certain task you are performing. To run a full scan of your system with Windows Defender, do the following:

Solution 4: hidden files

Solution 5: Checking for system file corruption

Sometimes, if your system files are corrupt or damaged, you won't be able to use much of your C drive's storage. System file corruption is critical and should not be taken lightly.
