The C drive is the primary hard drive partition that contains the operating system and related system files. You can check total disk space in Windows 11. It usually becomes full after using the device for some time. This is because it stores the following things:
- Windows operating system, system-related files, and settings
- Installed applications, Windows built-in programs, and downloaded software
- User data, such as documents, photos, and personal data stored on the desktop
Sometimes, you can move unallocated space to the C drive to get more space. There is a link for you to help.
Unallocated space can be used to extend another partition or create a new volume. In most cases, users may want to use the unallocated space to extend another partition.
As we can see, the operating system is located on the C drive. Over time, the operating system takes up more and more space as it needs to be constantly updated to improve performance.
On the other hand, we may save large work files and download large game videos or other files to the c drive for daily use. When too many large or cluttered files are stored on your computer, you may experience some serious performance problems.

There are basically two main directions to free up space on C drive. One is to extend the C drive, and the other is to free up space on the C drive. In this part, we provide eight ways for you to help with free up space on C drive.
So let's learn the specific ways one by
Extending the C drive is the most effective way to get more space on the C drive. Here, I would like to introduce a professional disk management tool for Windows to you, EaseUS Partition Master Professional.
It breaks the rules in Windows and gives more flexibility to extend/move partitions. Most importantly, EaseUS Partition Master Professional simplifies the whole process without causing data loss by adding adjacent or non-adjacent unallocated space to the C drive.
Step 1. Right-click on the D: partition with enough free space and select "Allocate Space".
Step 2. Select the target partition - C: drive and drag the partition panel rightward to add the free space from D: drive to C: drive. Then click "OK" to confirm.
Step 3. Click the "Execute Task" button and click "Apply" to start the process of moving free space from D: drive to C: drive.
EaseUS Partition Master is compatible with all Windows systems, and you can even free up disk space on Windows 8 with it. Besides adding the unallocated space to the C drive, EaseUS Partition Master still gets many other features, such as:
- Convert MBR to GPT
- Merge and resize Partitions
- Expand SSD C drive across disks
- Check file system errors and bad sectors
- Format hard drive and external hard drives
Therefore, if you are facing disk management problems, you can download it, and it is sure to help you a lot.
You can also transfer larger files to another drive to free up space on the C drive. There is a nice professional PC transfer software, EaseUS Todo PCTrans. It can help you transfer large files and programs to another drive efficiently. Let's see how.
Step 1. Run EaseUS Todo PCTrans on your PC. Choose "Large File Cleanup" > Click "Start" button to move on.
Step 2. Select the disk you want to scan, click "Scan."
Step 3. When the scan completes, files larger than 20M will be listed. Choose the wanted files and target drive to move. (You can choose the triangle icon to select destination or click "Browse" to pick the wanted place.)
Step 4. Click "Move" button, then check files on the pop window. Then click "Move" button again.
Windows comes with some great tools to help you keep your computer storage neat and tidy. Disk Cleanup is one of these tools. It allows you to delete data, such as temporary files, which can reach gigabytes (GB) of data over time. Follow the steps and have a try.
Step 1. Click "This PC." Then right-click the C drive and choose "Disk Cleanup" from the best match.
Step 2. It will show you a lot of files and file sizes taken by each file type. Then choose what you don't want. Then, click "OK."
Compact OS reduces the footprint of Windows applications to free up disk space, which makes sense in the context of Windows disk cleanup. But before using it, be careful to back up the important data on your C drive.
Step 1. Search for Command Prompt and choose "Run as Administrator."
Step 2. Then, type the command "Compact.exe /CompactOS:always" and hit Enter.
Step 3. It will take 20 minutes or so, and wait patiently.
- At any time you want to recover, you can run the opposite command: Compact.exe /CompactOS:never
Temporary files will also occupy the C drive space, so we need to delete them regularly. Now, let's see how.
Step 1. Press "Windows + I" to open Settings, and choose "System" and " Storage."
Step 2. Then, select "This PC (C:)" to analyze.
Step 3. Click on "Temporary files." Windows will list "Temporary files," "Recycle bin," "Downloads folder," and more folders in this section.
Step 4. Tick what you want to delete and then click "Remove files."
When files are deleted, Windows does not remove them from the drive. Instead, they are relocated to the Recycle Bin and marked as deleted. However, since the Recycle Bin gets larger over time, you can first empty it to free up space on the C drive.
Step 1. Open the "Recycle Bin" from the desktop.
Step 2. Select all the files and documents in the Recycle Bin, right-click on them, and select "Delete."
If you have installed some programs that were used to solve your problem but now you no longer need them, you can uninstall them to free up space on your C drive.
Step 1. Right-click on the Windows Start menu and click on Programs and Features.
Step 2. Then right-click on the program you no longer need and select "Uninstall."
Step 3. Repeat this process to remove the rest of the unnecessary applications.
Hibernation in computing is the process of powering off the computer while maintaining its state. If you have enabled Hibernate mode in Windows, it will also take up several gigabytes of space on your C drive, so follow the steps below to disable it.
Just open CMD and run the following command: Powercfg /hibernate off
Then, you can disable hibernation mode.
