Storage is one of the most important components that users think about when buying a new computer. With SSDs getting cheaper, users now have the option to go for much faster solid-state drives for relatively less cost. This also means that users can afford to install much higher capacities of storage on their computers.
However, many users are reporting that their C:\ drive keeps filling up for no reason on Windows 10. Here I will discuss why your hard drive keeps filling up and how you can solve this error on your device. Once you have tried this method you can also try boot time defrag which will help to keep the bloat away and speed up your computer.
We have shown a VIDEO walk through at the end of the post for easy solution.

Windows 10 is a multi-layered system software. There are many components that operate together in order to make it work properly for the user. There are many processes that the user does not even have to bother looking at, before using it. When so many components work together, some of these can go wrong from time to time.
There can be many reasons that your storage device can keep filling up for no reason. Take a look at the list of potential reasons why can be Windows 10 hard drives full for no reason.
If you too suffer from Windows 10 hard drive full without reason, here are some of the known working solutions that you can apply to clear up some space on your hard drive.
First, try freeing up some space with the help of third party junk cleaners like CCleaner and Treesize. Run a full system scan to analyze the disk space and check for any broken .dll files and missing extensions. These files contribute to taking up a lot of system storage and hence, maybe the reason why your hard drive keeps filling up.
If freeing up your system storage did not help you, there is very likely a virus or malware that is causing this error on your device. Infected systems are known to run out of storage, and the user generally has no idea why and where the storage is being used up.
If you do not wish to invest in third party premium antivirus software, you can opt from a host of free antivirus like Avast free antivirus, and anti-malware like Malwarebytes. Run a full scan, and delete any infected files.
You should see a significant increase in the storage space available.
However, if you see that there are no virus and malware on your device, or removing these files also did not free up storage, you can follow some other fixes, which may help you solve your hard drive keeps filling up error.
The Windows Component Store or the WinSxS folder contains the files and folders required to keep your Windows running and updated. You cannot delete it outright, but you can check our guide here ‘How to perform WinSxS Cleanup’.
Many users prefer hibernating to shutdown. When you hibernate your system, it takes a snapshot of the system files and drivers and saves them before shutting down your system. This allows your system to boot up faster and in the exact state that you left it in.
When hibernate is enabled, it reserves some of your disk space to save the hiberfil.sys file, the size of which is directly proportional to the size of your RAM. This file if not deleted properly, can take up some system storage space. You can disable the ‘hibernate’ feature to delete this misbehaving file.
You can use the disk cleanup tool provided alongside Windows to perform a system-level cleaning. Repeat this for all the partitions to clean up system files efficiently.
Performing the disk clean up will delete the unnecessary system files and the temporary files on your system, thereby providing you some important disk space in case you are running short on it.
Too many system restore points can also take up system storage space. If you have created the latest system restore point that is working fine, you may consider deleting the older ones to free up some space.
So there you have it. If your hard drive keeps filling up for no reason as well, now you know how to solve “C:\ drive keeps filling up” using one or a combination of the fixes given above. Tell us which method helped you in the comments below.
