On Windows 10, you can free up space on your computer in many different ways. Although nowadays, laptops and desktops include drives with multiple terabytes of storage, we always find a way to fill them up with documents, pictures, videos, apps, and games, causing the system to feel sluggish, problems saving files, and many other issues.
If your computer runs out of space, Windows 10 comes with tools if your computer runs low on space. For example, Storage Sense, OneDrive Files On-Demand, Compact OS, NTFS compression, and other features to delete unnecessary files, apps, and games can help reclaim space, improve performance, and resolve problems during updates.
This guide will walk you through the best ways to free up storage space on Windows 10 to store more files and install feature updates without issues.
1. Free up space clearing Recycle Bin on Windows 10
Windows 10 doesn’t erase files from the drive when you delete them. Instead, they are relocated to the Recycle Bin and marked for deletion. However, since the Recycle Bin can grow large over time, emptying its contents is the first thing you can do to free up space on your computer.
To empty the Recycle Bin to regain storage space on Windows 10, use these steps:
- Open Start.
- Search for Recycle Bin and click the top result to open the app.
- Quick tip: If the app does not appear in the result, you can open File Explorer (Windows key + E), type Recycle Bin, and press Enter in the address bar.
- Click the “Recycle Bin Tools” tab.
- Click the “Empty Recycle Bin” button.
- Click the Yes button.
Once you complete the steps, the system will free up around 10% of the drive capacity (assuming the bin is full).
Change Recycle Bin settings
Windows 10 reserves 10% of the available space for deleted files. Once the threshold is reached, the system will automatically delete files from the oldest to the newest. You can always adjust how much space the system should use for the Recycle Bin.
To reduce the space usage for the Recycle Bin, use these steps:
- Use the Windows + D keyboard shortcut to view the desktop.
- Right-click the Recycle Bin icon and select the Properties option.
- Select the Recycle Bin location you want to configure if you have multiple partitions. For example, Local Disk (C:) is the drive where Windows 10 is installed.
- Under the “Settings for selected location” section, select the Custom size option.
- In the “Maximum size (MB)” field, specify the maximum hard drive space in megabytes that Recycle Bin can use on the particular partition.
- (Optional) Check the “Don’t move files to the Recycle Bin. Remove files immediately when deleted” option if you want to delete the files from the drive skipping the Recycle Bin to minimize storage usage.
- Click the Apply button.
- Click the OK Button.
After you complete the steps, the Recycle Bin will be able to keep more or fewer files from a particular location, depending on your configuration.
2. Free up space removing junk files with Storage Sense on Windows 10
Storage Sense is a feature that allows the deletion of different types of junk files (including previous installation files after an upgrade and temporary files) to free up space on all the drives to make room to store other files and improve drive efficiency.
Enable Storage Sense
Although you can use Storage Sense manually, you can also enable the feature to run maintenance automatically.
To enable 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.
- Use the “Run Storage Sense” drop-down menu and select the best option for your situation:
- Every day.
- Every week.
- Every month.
- During low free disk space (recommended).
Once you complete the steps, Storage Sense will run automatically at your specified schedule to free up space and improve storage performance on Windows 10.
The option to enable the feature is also available through the “Storage” page. However, it only activates the default settings. Utilizing the Storage Sense settings page lets you configure how the feature should remove unnecessary content from your computer.
Delete unnecessary files with Storage Sense
To free up space using 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.
- Under the “Temporary Files” section, check the “Delete temporary files that my apps aren’t using” option.
- Use the Recycle Bin drop-down menu to specify how to clear already deleted files you do not need.
- Use the Downloads drop-down menu to specify how to clean up downloaded files.
- Quick tip: If you need to delete the most files, use the “1 day” option. The “Downloads” folder may contain valuable files you may have downloaded from the internet, which means that it is recommended to back up those files manually before running the feature.
- Under the “Locally available cloud content” section, use the drop-down menu to specify how long OneDrive content synced to the device becomes online-only.
- Quick note: This option is part of OneDrive Files On-Demand that allows you to access your documents, pictures, videos, and other files using File Explorer without needing to sync them to reduce the space usage. When the device is running low on space, you can use it to make files only available in the cloud. You will still see your files, but their content will only download when you need them.
- Under the “Free up space now” section, check the “Delete previous versions of Windows” option (if applicable).
- Click the Clean now button.
- Quick note: This option can free up close to 20GB of space, but the storage will vary from system to system.
Storage Sense will run and delete unnecessary files from the computer to reclaim more space after completing the steps.
Delete temporary files with Storage Sense
Storage Sense also deletes temporary system and app files that can help to reclaim several gigabytes of space on the computer.
To delete temporary files from the computer, use these steps:
- Open Settings.
- Click on System.
- Click on Storage.
- Under the “Local Disk (C:)” section, click the “Temporary files” item. (If the item is unavailable, click the “Show more categories” option.)

- Click the OK button.
- Click the OK button again.
Once you complete the steps, Windows 10 will compress the drive and any content already on the storage without reformatting.
When the feature is no longer needed, you can use the same instructions to disable compression, but in step 4, make sure to clear the “Compress this drive to save disk space” option.
8. Free up space disabling Hibernation on Windows 10
On Windows 10, Hibernation is a nifty feature that saves the data in memory onto the system drive before shutting down to preserve the current session upon resuming. Then you can pick up where you left off when the device returns online.
Although it is a convenient feature, it requires gigabytes of space to save the memory information into the hiberfil.sys file. If the device is running out of room, disabling Hibernation can help free up space for more critical files.
To disable Hibernation on Windows 10 to free up space, 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 on Windows 10 and press Enter: powercfg /hibernate off
Once you complete the steps, Hibernation will no longer be available, but you will have more space for other files.
In the future, you can always re-enable the feature with the same instructions, but on step 3, make sure to use the powercfg /hibernate on command.
9. Free up space compressing installation footprint of Windows 10
Compact OS is a tool that compresses the footprint of Windows 10 and apps. The feature is meant for devices with limited storage, but you can use the tool to quickly reclaim a few gigabytes of space when you do not have an external hard drive.
Warning: This is a friendly reminder that modifying system files is risky and can cause irreversible damage to your installation if you do not do it correctly. Before proceeding, making a temporary full backup of your PC is recommended.
To shrink the size of the Windows 10 installation and apps with Compact OS, 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: compact.exe /compactOS:always
After you complete the steps, the process will reclaim around 2GB of storage, slightly improving performance.
When the feature is no longer needed, you can always revert the changes using the same instructions, but in step 3, make sure to use the compact.exe /compactOS:never command.
10. Free up space rebuilding search indexer on Windows 10
The Windows Search database can sometimes grow very large because of the amount of content that needs indexing or indexing issues, which can be why the system drive is running out of space. If this is the case, clearing and rebuilding the database and modifying the index items can significantly reduce storage usage on Windows 10.
To rebuild the index of Windows 10 to free up space, use these steps:
- Open Settings.
- Click on Search.
- Click on Searching Windows.
- Under the “More Search Indexer Settings” section, click the “Advanced Search Indexer Settings” option.
- Click the Advanced button.
- Click the Index Settings tab.
- Under the “Troubleshooting” section, click the Rebuild button.
- Click the OK button.
Once you complete the steps, the system will clear and rebuild the Windows Search feature’s index database, which can significantly reclaim a lot of space.
The only caveat with this process is that during the rebuild, searches using the Taskbar, File Explorer, and across Windows 10 might be incomplete until files are re-indexed.
Configure indexer
You can also minimize the space by preventing Windows Search from indexing specific locations.
To remove indexing folder locations from Windows Search, use these steps:
- Open Settings.
- Click on Search.
- Click on Searching Windows.
- Under the “More Search Indexer Settings” section, click the “Advanced Search Indexer Settings” option.
- Click the Modify button.
- Click the Show all locations button.
- Clear the options for apps to exclude from the index database.
- Quick note: Generally speaking, you never want to index any kind of application.
- Expand the “C:” drive and clear the folder you do not wish to appear in search to reduce the database storage usage.
- Click the OK button.
- Click the Close button.
After completing the steps, Windows Search will update the database, hopefully reducing its footprint and making space for other files.
11. Free up space deleting users no longer sharing device
If you share the computer with others, it may be possible to free up space by deleting accounts that no one is using anymore.
To delete a user account and files on Windows 10, use these steps:
- Open Settings.
- Click on Accounts.
- Click on Family & other users.
- Select the account no longer in use.
- Click the Remove button.
- Click the “Delete account and data” button.
Once you complete the steps, the profile and data will be removed from the computer, regaining more space for other files. You may need to repeat the steps to delete other accounts on Windows 10.
12. Free up space disabling Reserved Storage on Windows 10
“Reserved Storage” on Windows 10 is a feature that sets apart several gigabytes of space for updates, system cache, and temporary files. When new updates are available, the system automatically cleans up the storage to minimize problems during other updates.
Although this is a great feature to minimize problems during updates and upgrades, it takes away space you could use to store more documents, pictures, and videos. If you understand the feature and prefer not to use it, you can disable it to free up space. The only caveat with this method is that once you disable the feature, the changes will apply during the next feature update of Windows.
Important: Only use these instructions if you understand the feature. Otherwise, it is not recommended to disable Reserved Storage as it may cause issues during updates.
To disable Reserved Storage on Windows 10, use these steps:
- Open Start.
- Search for PowerShell, right-click the top result, and select the Run as administrator option.
- Type the following command to confirm whether the feature is enabled and press Enter: Get-WindowsReservedStorageState
- Type the following command to disable the feature and press Enter: Set-WindowsReservedStorageState -State disabled
After completing the steps, the feature will turn off on Windows 10, allowing you to reclaim around 7GB of space after the next feature update of Windows 10.
In addition to all these different ways to free up drive space, sometimes malware can cause storage problems. If you notice strange behaviors and the hard drive is running low in space, a virus may be causing the problem. If this is the case, you can use these instructions to scan, detect, and remove any malware causing storage issues.
