Solution 2: Delete Junk Files by Storage Sense

If you have a Windows 10 #1903 (released on May 10, 2019) or a newer version, then you can also take the assistance of Storage Sense. It is an inbuilt Windows Utility tool that can help you free up space on C drive automatically.

Solution 3: Delete Temp Files by Disk Cleanup

While working on your Windows system for a while, chances are that you might end up accumulating a lot of temporary data. Although temp files are used to store certain vital details and make the overall experience smoother, they can also consume a lot of space. The best way to clear C drive is by cleaning its temporary data in regular intervals by using the Disk Cleanup Utility.

1. There are multiple ways to access the Disk Cleanup app. One of the easiest ways is to look for it from the start menu.

Solution 4: Empty Recycle Bin

Therefore, you can check the Recycle Bin storage and clear it to free up space on C drive. While doing so, just make sure that you don’t get rid of any important file.

1. There are different ways to empty Recycle Bin. For instance, you can just select its icon from the desktop, right-click, and choose the “Empty Recycle Bin” option.

Solution 5: Move Data to Another Hard Drive

If you are not sure of what you can delete from your system, then this would be an ideal option. Simply get another hard drive (like an external hard disk) and move your important files to it instead. In this way, you can keep your files to another location separately without losing them from your system.

1. Simply connect the second hard disk or an external hard drive to your system and wait for it to be detected.

2. Now, go to My Computer > C Drive and browse the data you wish to get rid of. Cut it from here and paste it on the hard drive.

3. If you want, you can also right-click the file/folder you wish to move, go to the “Send to” option, and select the connected hard disk as a source. This will directly send this file/folder to your hard drive.

Solution 6: Disable Hibernation in Windows 10/7

A lot of Windows users put their system on hibernation to save power and time. Though, it can backfire – since the feature creates a dedicated system file (hiberfil.sys). During the hibernation, the file would store all the vital details of the system so that you can start from where you left off before. Ideally, it is not recommended to turn off hibernation, if you are used to it. Nevertheless, if you wish to learn how to clean C drive, then you can give this option a try.

1. To turn off the hibernation feature, you need to launch the Command Prompt first. Go to the Start menu to do it. Just make sure that you launch Command Prompt as an administrator.

2. After when the Command Prompt is launched, simply type and enter the “powercfg –h OFF” command.

3. Alternatively, you can also type the “powercfg /hibernate off” command and press enter. This will automatically disable the hibernation mode on your system.

Solution 7: Compress Installation Data

1. To start with, simply launch Windows Explorer > My Computer and select your C drive.

2. Right-click and visit its Properties. Under the General tab, you can see an option for “Compress this drive to save disk space”. Enable this and implement the changes to compress the drive.

In the latest Windows systems (like 7, 8, or 10), there is an option to restore the system files after an unwanted crash. While most of the experts would recommend keeping the feature enabled, it can end up taking a lot of space on your drive.

Solution 9: Compress System Files

We have already listed how Windows can compress certain files to free up space on C drive. Though, just like compressing the installation files, it is not recommended to follow this suggestion as it might affect the overall processing of your system. Ideally, you should consider it as a last resort when you have to clear C drive data immediately.

Solution 10: Extend the C Drive Storage

If nothing else would seem to work, then you can also extend the storage of C drive as well. Beforehand, just make sure that there is enough available space on the disk. If not, you can format a partition and have available space that can be merged to the C drive. If your C drive is running out of space, then follow these steps:.

1. To begin with, launch the Disk Management application on Windows. You can find it from the Start menu.

2. As the Disk Management window will open, you can view the storage allocated to each partition and the available free space as well.

3. Right-click the C drive option from here and go to the “Extend Volume” feature.
