On
Windows 10
, you can quickly free up space on your computer’s hard drive in a number of ways, and in this guide, you will learn how. When the “C” drive is full without reason, or the device starts
showing signs that it’s running out of space
, removing unnecessary files is critical to have more room for other files and prevent performance problems. Using a computer without enough space will slow down the system and cause errors.
Using more than 70 percent of the hard drive’s total capacity is never a good idea
, whether the device features a Solid-State Drive (SSD) or a traditional Hard Disk Drive (HDD).
If you have to free up disk space on your computer, Windows 10 offers several ways to complete this task. Some of the easiest methods include using the Temporary file settings, Storage Sense, and you even use the legacy Disk Cleanup. You can reclaim additional space by uninstalling apps you don’t use, disabling hibernation, and resetting the search index.
You can also use other features like NTFS and CompactOS to compress system files and apps to reclaim additional storage.
In this
guide
, I will outline the most effective ways to declutter the hard drive on Windows 10.

10 Transfer files to another drive
1. Delete temporary files
The
“Temporary files”
settings allow you to quickly delete unnecessary files to run Windows 10 to free up hard drive space. For example, leftover files after installing a new version, upgrade logs, error reporting, temporary Windows installation files, and many others.
To delete temporary files to free up hard drive space on Windows 10, use these steps:
Open
Settings
on Windows 10.
Click on
System
.
Click on
Storage
.
Click the
Temporary files
setting.
Check the temporary files to free up space on Windows 10, such as “Windows Update Cleanup,” “Recycle Bin,” “Windows upgrade log files,” “Temporary files,” and “Temporary Windows installation files.”
Click the
Remove files
button.
Once you complete the steps, the junk temporary files will be removed from your computer, freeing up space for more important files on Windows 10.
2. Run Storage Sense
“Storage Sense”
is another feature that can free up space automatically whenever the “C” drive is low on space. It does this by deleting temporary system and apps files, emptying the “Recycle Bin” and “Downloads” folders, and converting files synced to OneDrive to online-only content.
To free up space with Storage Sense on Windows 10, use these steps:
Open
Settings
.
Click on
System
.
Click on
Storage
.
Under the “Storage” section, click the
“Configure Storage Sense or run it now”
option.
Turn on the
Storage Sense
toggle switch.
Check the
“Delete temporary files that my apps aren’t using”
option.
Select when to run Storage Sense automatically, including
“Every day,”
“Every week,”
“Every month,”
or
“During low free disk space”
Under the “Temporary files” section, check the
“Delete temporary files that my apps aren’t using”
option.
Choose when to delete files from the Recycle Bin using the “Delete files in my recycle bin if they have been there for over” setting. (The
“Never”
option disables the feature.)
Select when to delete files from the
“Downloads”
folder using the “Delete files in my Downloads folder if they have been there for over” setting.
Choose when the OneDrive files synced to your computer will become online-only files using the “OneDrive” setting to free up space.
Check the
“Delete previous versions of Windows”
option (if applicable).
Click the
Remove
button.
Once you complete the steps, Windows 10 will free up hard drive space, making more room to store other files. Also, since you are enabling the feature, Storage Sense will run automatically when there is a low amount of available drive space.
3. Run Disk Cleanup
The
“Disk Cleanup”
tool has been available for a long time, and it allows you to select and remove unnecessary files from your computer, similar to the “Temporary files” settings.
To remove temporary files on Windows 10 from Disk Cleanup, use these steps:
Open
File Explorer
.
Click on
This PC
from the left navigation pane.
Right-click the drive with the Windows 10 installation and select the
Properties
option.
Click the
Disk Cleanup
button.
Click the
“Clean up system files”
button.
Check the items you want to delete. For instance,
“Temporary Windows Installation Files,” “Windows upgrade log files,” “Recycle Bin,” “Temporary Files,”
and
“System created Windows Error Reporting.”
Click the
OK
button.
Click the
Delete Files
button.
Once you complete the steps, temporary files will permanently be deleted from your computer, making room for new files.
4. Uninstall apps
Uninstalling apps from your computer can help free up disk space on your computer. Over time, you may accumulate a lot of apps you no longer use or need, and these can take up valuable storage space. By uninstalling them, you can reclaim space and improve the performance of Windows 10.
To uninstall an app on Windows 10, use these steps:
Open
Settings
.
Click on
Apps
.
Click on
Apps & features
.
Under the “Apps & features” section, select the app (or game).
Click the
Uninstall
button.
Click the
Uninstall
button again.
After you complete the steps, the app will be removed to free up space on your computer. You can also
check out this guide
with many more methods to uninstall applications.
5. Disable hibernation
Hibernation is a feature that allows the computer to save its current state to the hard drive and power off completely. When the computer is turned back on, it can quickly resume from where it left off. However, this feature requires a large amount of space to store the hibernation file. When disabling hibernation, you can free up valuable space on Windows 10.
To disable hibernation on Windows 10, use these steps:
Open
Start
.
Search for
Command Prompt
, right-click the top result, and select the
Run as administrator
option.
Type the following command to disable hibernation to free up space and press
Enter
:
Once you complete the steps, the feature will be disabled, potentially freeing up several gigabytes of disk space on your computer.
6. Clear search index database
The search index is a database that stores information about the files and folders on your device. Although it helps to show results quickly when using the Windows Search feature, it can also take up a significant amount of space over time. If you reset the search index, you can clear out unnecessary data and start fresh with a smaller, more efficient database. This can help improve system performance and free up valuable storage space for other files and apps.
To reset the search index on Windows 10, use these steps:
Open
Settings
.
Click on
Search
.
Click on
Searching Windows
.
Click the
“Advances Search Indexer Settings”
option.
Click the
Advanced
button.
Under the “Troubleshooting” section, click the
Rebuild
button to delete the database.
Click the
OK
button.
Click the
Close
button.
Once you complete the steps, the index database file will be deleted and replaced with a new, smaller version, freeing up some additional space on Windows 10.
7. OneDrive enable free up disk space
OneDrive offers the “Files On-Demand” feature that frees up space on the drive by deleting already uploaded files from your local storage while maintaining access to the files from File Explorer. (However, you will need an internet connection to access the files.)
To enable files on-demand in OneDrive to reclaim storage on your computer, use these steps:
Right-click the
OneDrive
icon in the Taskbar.
Click the
Settings
option.
Click on
Sync and backup
.
Click the
Advanced settings
item.
Click the
“Free up disk space”
button under the “Files On-Demand” section.
Click the
Continue
button.
After you complete the steps, OneDrive will delete those files already uploaded to your cloud account, but you can still access the files from File Explorer with an internet connection.
8. Enable NTFS compression
The NT File System (NTFS) includes a feature that compresses the contents of a partition, folder, and even files individually. You can use this option to reduce the footprint of data on the drive. However, if the file is already using some sort of compression, it’s unlikely that this method will reduce the size even further.
Since the feature will compress and uncompress files on demand, this may affect system performance.
To enable NTFS compress on a folder or partition to optimize space usage on Windows 10, use these steps:
Open
File Explorer
.
Open the drive or folder location.
Right-click the item and select the
Properties
option.
Click the
Advanced
button.
Check the
“Compress contents to save disk space”
option under the “Compress or Encrypt attributes” section.
Click the
OK
button.
Click the
Apply
button.
Select the
“Apply changes to this folder, subfolders and files”
option.
Click the
OK
button.
Click the
OK
button one more time.
After you complete the steps, the system will enable compression on the partition or folder to free up space on the drive.
9. Enable CompactOS
On Windows 10, CopactOS is a feature that compresses the installation of the operating system and apps on devices with limited capacity. You can use this feature to reclaim additional storage space.
To enable CompactOS to reclaim storage space on Windows 10, use these steps:
Open
Start
.
Search for
Command Prompt
, right-click the top result, and select the
Run as administrator
option.
Type the following command to enable Compress OS and press
Enter
:
Once you complete the steps, the feature will compress the system files and apps to free up additional space on Windows 10.
10. Transfer files to another drive
Alternatively, you can connect a secondary storage using an external USB drive or internal hard drive to transfer your files to clear space in the system drive.
To free up space relocating files to another drive on Windows 10, use these steps:
Open
File Explorer
.
Open the folder with the files to transfer.
Select the files and click the
Cut
button from the command bar.
Open the new drive location.
Click the
Paste
button from the command bar.
Once you complete the steps, the system drive will have more space for other files. You may have to repeat the steps to transfer other files and folders. In addition to using File Explorer, you can perform the same task faster using commands with
the Robocopy tool
.
If, after using these methods, the computer continues to have low drive space, you may want to try
resetting the system
or performing a
clean install of Windows 10
. You can also Free up storage space by moving large files, such as videos, images, and virtual machines, to an external hard drive.
