Moreover, it is recommended that you do not use more than 70 percent of the total disk space (especially on the C/boot driver) to avoid performance issues. If you run out of free space on your computer, there are many ways to create more room for data and improve its performance. Windows 11 has integrated tools to help you manage your storage devices more robustly. These include Storage Sense, Cleanup Recommendations, and native compression mechanisms. Not only that, the Windows Settings application is now more advanced than ever, using which you can gain complete insight into the components taking up your storage space. If you are experiencing performance issues due to low disk space on your C drive, or want to fix the “low disk space” warning prompting now and then, perform the given methods to create space and get rid of the prompt. Note: The screenshots and methods listed below are directed for Windows 11, but many are also applicable to Windows 10.
Check What is Consuming Storage Space
Before we begin creating room on our disk, let us check what is consuming it in the first place. Windows 11 makes this easier by providing an interface to view the different types of data taking up space on your disk.

A typical Windows 11 clean installation takes nearly 30GB of space on your disk. What is taking up the rest? Here are the steps to find out: This information gives a glimpse of what data is important and what can be removed to create significant free space on your drive. If you are using an earlier version of Windows, you can use WinDirStat disk space analyzer to check exactly what is taking up space on your drive. You will now see a breakdown of what is consuming your storage disk in segmented categories.
How to Free Up Hard Drive Space in Windows
Remove/Delete Temporary Files
Temporary files are created when the system performs a certain task. They are supposed to be removed automatically, but occasionally are not, eventually consuming a lot of space. Temporary files can be safely removed, without having any negative effects on the operating system. Note that these also include temporary Windows update files that are no longer needed. You can delete these files using the Disk Cleanup tool by following these steps: The selected data will now be deleted, freeing up space on your disk. If the created space is insufficient, you can continue to perform the following methods to free up more space on the drive. On this Settings page, you will likely see the following options to select and remove:
Cleanup Recycle Bin Delivery Optimization Files Thumbnails Microsoft Defender Antivirus Temporary Internet Files Temporary files Windows error reports and feedback diagnostics DirectX Shader Cache Previous Windows installation(s) Temporary Windows installation files
Perform Cleanup Recommendations
The Settings app in Windows 11 also suggests a few actions you can take to free up additional space on the hard drive. You can manually choose whether to perform those actions or not. To act on the cleanup recommendations, follow these steps: The selected data will now be removed.
Temporary files Large or unused files Files synced to the cloud Unused apps
Enable Storage Sense
Storage Sense is a Windows 11 feature that automatically performs cleanup tasks to keep your disk utilization to a minimum. Using this feature, you can control when some files and folders are automatically deleted when they are no longer in use. Perform the following steps to use Storage Sense to free up disk space on your drive:
Perform Disk Cleanup
Disk Cleanup is a built-in feature in Windows 10 that wipes out any unnecessary data the system no longer requires, automatically. You can perform the steps below on the volume that is low on free disk space: This will allow Windows to automatically delete files and folders when it detects that the space is running low, or on a specified schedule. Here, you can set when Storage Sense should run, and when to empty the recycle bin and the Downloads folder. Note: This method will not apply to Windows 11 anymore.
Disable Hibernation Mode
The hibernation mode in Windows puts the computer in deep sleep while maintaining all of your open data in a file called “hiberfil.sys.” This hidden file is stored in the system drive and can significantly grow in size. Disabling the hibernation mode automatically removes the file, freeing up space. You can choose from the following categories:
Windows Update Cleanup. Microsoft Defender Antivirus. Downloaded Program Files. Temporary Internet Files. Windows error reports and feedback diagnostics. DirectX Shader Cache. Delivery Optimization Files. Device driver packages. Language Resource Files. Previous Windows installation(s). Recycle Bin. Temporary files. Thumbnails.
The deletion process should now begin. The image below shows the size of the hiberfil.sys file on our PC: Disabling this feature would automatically create almost 16 GB of free disk space on our boot drive. To disable hibernation, follow these steps:
Shrink/Disable Pagefile
The Pagefile is another hidden system file whose purpose is to compensate for any shortages of RAM. Occasionally, the data in your system’s memory takes refuge in the Pagefile, which is on your storage drive (C drive), and subsequently takes up significant space. Although we do not suggest that you disable Pagefile entirely, since it is an important feature that contributes to the normal functionality of the operating system, it can still be done if absolutely necessary. You can determine the optimal Pagefile size and then use the guide below to set it up or disable it entirely. Here are the steps to disable or shrink the pagefile size: When the computer reboots, you will notice that the free space on the system drive has increased the same as the Pagefile size has been reduced. Alternatively, select the “No paging file” radio button to disable the feature entirely.
Compress Drive using Compactor
Although Windows allows the option to compress the data inside a drive using native methods, we do not suggest you use it. Rather, we suggest that you compress “selective” data using Compactor. Compactor is an easy-to-use Graphical User Interface (GUI) based application that uses the existing Windows compact.exe command-line tool to compress the data selected. Since it is based on an existing Microsoft command, it is completely safe to use. Why prefer Compactor over the native compression options? The biggest disadvantage of using the system compression option is that it compresses all the contents of the drive. This is not recommended for the system drive. It will make the system slow because the system will have to decompress the files before opening them. Using the Compactor utility is pretty simple. However, the creator of the utility takes no responsibility for your data. Hence, we would recommend you create a restore point if things go sideways. You can also use our top selection of disk imaging and backup software so you never lose your data or operating system again. Perform the following steps to compress your data and free up some storage space: You will be prompted when the compression is complete. You may now notice that the files and folders occupy less space on the disk than before, as in the comparison below:
Download Compactor for 64-Bit Windows Download Compactor for 32-Bit Windows
You may also select an entire partition by clicking on it, and then click “Select Folder.” The application will now display the compression summary if you perform it. This step may take a few minutes depending on the type of compression and folder size.
Enable OneDrive Files On-Demand
OneDrive has a “Files On-Demand” feature that does not save a file synced to OneDrive locally, but rather fetches it from the cloud over the internet when it is opened. Of course, it requires an active internet connection to be able to get the desired file. Enabling this feature will save disk space since the files only exist at a remote cloud location. Here’s how to enable it: You can now move your files and folders to the OneDrive folder using Windows Explorer, freeing up space on your local PC.
Rebuild Indexing Library
Indexing is the process of storing file data, such as its content, metadata, dates associated, etc. so that the operating system can perform a “lookup” when the user performs a search. Over time, this stored data can become large in quantity, even though some of the indexed content may no longer exist. You can thus try to free up some space by rebuilding the indexing library or removing indexed files and folders from the list. Click on the respective link to learn how to do it.
Uninstall Unused Apps
You can also create some free space on your storage drive by removing any apps or app data that is no longer in use. Here is how: The application will now be removed from your computer, freeing up space. You can repeat these steps to remove even more unused applications from your PC. Alternatively, you can also uninstall apps and programs from the Programs & Features applet by typing in “appwiz.cpl” in the Run Command box.
Delete Unused Language Packs
Language packs in Windows can also consume a significant amount of storage space on your PC. If one or more languages are no longer in use, you can remove them using the following steps to free up storage space: The language pack will now be deleted from your computer, creating additional free space. Note: The language to be removed should not be the current display language.
Delete Unused User Accounts
If your PC has local user accounts that are no longer in use, you can simply delete them. This will remove any files and folders those accounts contain that are no longer needed. Follow these steps to delete unused user accounts: Repeat these steps and remove all the user accounts and their data that are no longer needed.
Scan for Malware
It may be possible that a potential virus is creating hoax files to slow down your computer. Therefore, it is recommended that you perform a deep system scan and get rid of any trojan horses or malware. Here is a list of the top antivirus software to use to perform the scan. In case you are proceeding to purchase antivirus software, here are the 17 aspects you should always consider. You can also use the built-in Windows Defender in Windows to scan your computer for malware. If you want to, open the Windows Security page in the Settings app, and then click Virus & Threat Protection. Next, click the Quick Scan button to perform a scan. Alternatively, you can also click Scan options below it to select a deep scan of your OS.
Final Thoughts
Performing some or all of the methods above will definitely create some free space on your computer. The Windows operating system provides several native ways to free up and manage your storage space. This is why we suggest you avoid using third-party tools on this particular OS to create some storage space. Not that third-party tools can cause problems, because some of them are trusted and efficient, but that there is no need to use an external tool to perform the same tasks you can achieve using Windows native tools. That said, our methods given in this post will automatically clear the recycle bin and other temporary files. Therefore, we have not given a standalone method for doing so.
