Free up drive space in Windows 10

If your PC is running low on free space, you might not be able to install important Windows updates, and your PC’s performance may be affected. Here are some ways to free up space so you can keep your PC up to date and running smoothly. These suggestions are listed in order, so start with the first one, see if that helps, and then continue to the next one if it doesn’t.

To check the total disk space left on your Windows 10 device, select File Explorer from the taskbar, and then select This PC on the left. The available space on your drive will appear under Devices and drives.

Note: If you follow the steps below and continue to have trouble updating Windows because of low disk space, resetting or reinstalling Windows might help. For more info, see Reinstall Windows 10.

If you used Disk Cleanup to free up space on your device and then see a Low Disk Space error, it’s possible that your Temp folder is quickly filling up with application (.appx) files that are used by Microsoft Store. For more info, see Low Disk Space error due to a full Temp folder.

Storage Sense can automatically free up drive space for you by getting rid of items that you don’t need, like temporary files and items in your Recycle Bin. For more info, see Manage drive space with Storage Sense.

If your system doesn’t have Storage sense, you can use the Disk Cleanup tool to delete temporary files and system files from your device.

In the search box on the taskbar, type disk cleanup, then select itfrom the results.

Select the check box next to the type of files you want to delete. (To view a description of each type of file, select the name.) By default, Downloaded Program Files, Temporary Internet Files, and Thumbnails are selected. Be sure to clear those check boxes if you don’t want to delete those files.

To free up even more space, select Clean up system files, and then select the type of system files you want to delete. Disk Cleanup will take a few moments to calculate the amount of space that can be freed up.

Note: If it’s been fewer than 10 days since you upgraded to Windows 10, your previous version of Windows will be listed as a system file you can delete. If you need to free up drive space, you can delete it, but keep in mind that you’ll be deleting your Windows.old folder, which contains files that give you the option to go back to your previous version of Windows. If you delete your previous version of Windows, this can’t be undone. (You won’t be able to go back to your previous version of Windows.)

After you’ve selected the types of files you want to delete, select OK, and then select Delete files in the confirmation window to start the cleanup.

There’s also an option in Disk Cleanup to Compress your OS drive. Selecting this option compresses the drive on which Windows is installed, helping you gain extra space to install important updates. This action does not delete the contents of this drive, and you shouldn’t experience problems opening and saving files from the compressed drive.

After you install the update, you can manually decompress the OS drive at any time. To do this, select File Explorer from the taskbar, and in the left pane, select This PC. Right-click or tap and hold the OS drive (usually disk C), and then select Properties on the shortcut menu. Clear the Compress this drive to save disk space check box, and then select Apply > OK.

Windows 10 may indicate that it needs more space to get the latest Windows 10 feature update. You can use an external storage device to help you complete the update.

Note: You may need to use a micro-USB adapter if your device doesn’t have a standard USB port.

Personal files such as videos, music, photos, and documents can take up a lot of space on your device. To see which files are using the most space:

Select File Explorer from the taskbar and find the files you want to move.

Under This PC in the menu on the left, select a folder to see what files are saved in it. The Videos, Music, Pictures, and Downloads folders usually contain the largest files that you’ve saved to your device.

To see the size of the files in a folder, select View > Details. Right-click in the open space and then select Sort by > Size to show the largest files at the top of the list.

If there are files you no longer need on your device, you can either delete them or move them to an external storage device like a USB drive or an SD card.

Note: If you delete any files, remember to empty the Recycle Bin to completely remove them from your device and free up space.

To move photos, music, videos, or other files that you want to keep but don’t use very often, consider saving them to an external storage device like a USB drive or an SD card. You’ll still be able to use them when the drive is connected, but they won’t take up space on your PC.

Connect an external storage device like a USB drive or SD card to your PC.

Select File Explorer from the taskbar and go to the folder that contains the files you want to move.

Select the files, select the Home tab, and then select Move to > Choose location.

Select the external storage device you connected in the location list, and then select Move.

Saving new files to another drive will help prevent low space problems on that drive in the future, so you won’t have to move your files to another drive repeatedly. Instead of saving all your new files to the default drive, you can save some of them to a different drive that has more free space.

Under More storage settings, select Change where new content is saved.

For each content type, select a drive from the drop-down menu. If the drive you want to use isn’t listed there, make sure it’s connected to your PC.

Note: OneDrive Files On-Demand requires Windows 10 version 1709 or later and OneDrive client version 17.3.7064.1005 or later. To see which version of Windows you’re running, select Start > Settings > System > About . To see which version of the OneDrive client you have installed, see Which version of OneDrive am I using?
Open About settings

You can save space by turning on OneDrive Files On-Demand, which stores a smaller placeholder file on your hard drive instead of the full-size file that’s stored in your OneDrive account in the cloud. You’ll be able to get to your OneDrive files from your PC without having to use up hard-drive space downloading full-size versions of them all. See Learn about OneDrive Files On-Demand for more info.

Sometimes a virus or other malware can consume significant hard-drive space by corrupting your system files. If you suspect your PC is infected with malware, use an antivirus program like Windows Defender to run a virus scan and cleanup. If this doesn’t fix the problem, you might need to reset your PC.

If you’ve followed the instructions here but still need help freeing up space on your device, you can contact Microsoft support to chat with a support agent. This is also recommended if your attempts to free up drive space trigger particular error codes that you need help resolving.

The following questions concern low disk space and Windows Update specifically. Learn more about Windows Update.

When there isn’t enough free space available to install an update, a pop-up notification will prompt you that additional space is required to install the update.

When you select Fix issues, you’ll be informed about how much additional space is needed. You’ll also be notified that you can use an external storage device so that you don’t need to free up quite as much space on your system drive. Learn how to free up space to install Windows updates.

The total free disk space your device requires to complete an update varies. Typically, feature updates require 6 GB–11 GB or more of free space, while quality updates require 2 GB–3 GB or more. Learn about the difference between a feature update and a quality update.

You need disk space to download the update, download new versions of any optional features and languages that are currently installed, and to apply the update. Additional space is temporarily required to support removal of the update (typically for 10 days). This space can be reclaimed after the update is completed. To do this, Select Start > Settings > System > Storage > Free up space now.
Open Storage settings

The update is compressed to reduce download size.

Note: For devices with reserved storage, an update will first use the reserved storage space before using other disk space. For more info, see How reserved storage works in Windows 10.

The space required to complete a feature update depends on two factors: which update path is followed and the size of optional content and other updates that apply to your PC when the feature update is installed.

Note: For devices with reserved storage, an update will first use the reserved storage space before using other disk space. For more info, see How reserved storage works in Windows 10.

Windows follows three different feature update paths, depending on the amount of disk space currently available.

1. For PCs with plenty of free disk space

Windows automatically tries to complete more of the update process in the background while you use your PC. This significantly reduces the time your PC will be offline (or unusable) during the update, although it might temporarily use more disk space to complete the update. Learn more about our efforts to reduce offline time during updates (English only at this time).

2. For PCs with limited free space but still enough to complete the update automatically

Windows will automatically optimize for reducing the amount of free disk space required to install the update. This will result in a longer offline install time.

3. For PCs that don’t have enough space to automatically install the update

Windows will prompt you to free up disk space or use external storage to temporarily extend the storage on your PC. If you use an external storage device, Windows won’t need as much free space on the system drive as it temporarily uses your external storage.

Across each of these update paths, the total amount of free disk space required will vary, depending on the optional content installed and other updates that apply to your PC. For example:

Optional features. Many optional features available for Windows are pre-installed or acquired on demand by the system, or manually by you. You can see which ones are installed on your PC by going to Settings > Apps > Apps & features > Manage optional features.
Open Optional features settings
These features range in size from less than 1 MB to almost 2 GB for the Windows Mixed Reality portal. You can reduce the amount of space required to install a feature update on your PC by uninstalling optional features you aren’t using.

Languages installed. Windows is localized into many languages. Although many people only use one language at a time, some people switch between two or more languages. You can see which languages are installed on your PC by selecting Start > Settings > Time & Language > Language .
Open Language settings
During each update, all language resources and any associated typing, text-to-speech, speech-to-text, and handwriting recognition resources must be updated. The content for each language can range from about 175 MB to more than 300 MB. You can reduce the amount of space required to install a feature update on your PC by uninstalling languages you aren’t using.

Driver updates. OEMs and other hardware partners sometimes publish new graphics, networking, audio, and other drivers in conjunction with the new OS update. The size of these drivers can vary significantly, depending on your PC and on which drivers have been updated.

OS quality updates. During a feature update, Windows tries to download and automatically install the latest quality update so that your PC is fully up to date when you start using it. Shortly after the feature update is released, the quality update for that feature update could be as small as a few hundred MB, but as more quality and security changes are implemented, the quality update can increase in size to 1 GB or more.If your PC is short on disk space, you can download and install the quality update after the feature update is complete.

Finally, Windows Update will temporarily disable hiberfile.sys, pagefile.sys, and other system files in order to use the space these files typically consume to apply the feature update. Any files that are disabled to apply the update will be automatically re-enabled when the update is complete. Because these files vary in size depending on how you use your PC and the amount of RAM your PC has, even in cases where two different PCs have the exact same OS image, the amount of free disk space required to complete an update may vary.

The combination of update path and features means there’s a wide range of free disk space required to complete an update. Here are a few examples for PCs updating to Windows version 1803:

Optimized for reduced offline time

Optimized for minimal disk space

Optimized for minimal disk space with external storage

Minimal optional features, languages, and updates

8 Top Tips: How To Free Up Disk Space On Windows Computers

How to clean up your Windows computer hard drive

Last Updated : 4th February 2021 | Author: Wide Angle Software Dev Team

What is taking up space on my hard drive?

If you haven’t got space on your computer for that new app or game, or the clutter on your hard drive is just driving you crazy, you’re not alone.

With the introduction of SSDs (solid-state drives) offering loads less space than traditional mechanical hard drives, in conjunction with games and applications requiring more and more disk space, your hard drive can easily become full.

In this article, we’ll go through the top 8 ways to clean up your Windows hard drive: finding out what is taking up so much space on your hard drive, reducing the clutter and creating space for those all important new applications or files. So, without further ado, let’s get started…

Jump straight to:

New Update: Windows Storage Sense

Since the initial publication of this article, Microsoft have been busy working on the issue of saving space on people’s computers. The amalgamation of their hard-work comes in the form of «Storage Sense» — An all-in-one, intuitive feature which cleans a computer of unwanted files easier and more efficiently than ever before!

If you are using Windows 10, you can use this feature in place of the «Windows Disk Cleanup» and «Take out the Trash» sections of this article. This is because these steps are now covered by Storage Sense (Disk Cleanup and Recycle Bin are still available too if you prefer to use those, or if you are running another version of Windows like Windows 7). Let’s see how to use this new feature.

• Use Storage Sense on demand
• Set up Storage Sense to run automatically

How to use Storage Sense on demand

If you don’t need to clean up your computer files very often, or if you want control over exactly what files are deleted, I would recommend using Storage Sense on demand, rather than allowing it to run automatically. Here’s how:

1. Click your Windows icon and open «Settings».
2. Click «System».
3. Select «Storage» from the list on the left.
4. Under «Storage Sense», click «Free up space now».

Your computer will be scanned for temporary files which may want to delete.

Once the scan is complete, tick the files you want to delete.

Click «Remove Files» to permanently delete the files from your computer.

How to configure Storage Sense to run automatically

If you often need to clean up your computer for temporary files and like the sound of automating the process, I would recommend using Storage Sense to automatically and periodically clean up your files. Here’s how:

1. Click your Windows icon and open «Settings».
2. Click «System».
3. Select «Storage» from the list on the left.
4. Under «Storage Sense», click «Change how we free up space automatically».

Choose your preferences (set when you would like Storage Sense to run, what to delete, and how long).

Once you’re happy with your selections, toggle Storage Sense on.

Click «Clean Now» if you want to start your first scan now.

The tool is great, right? It’s a massive improvement over the separate, hard-to-find features from before. However, it still does not deal with duplicate files, uninstalling unused programs and more. Jump to: finding and deleting duplicates now >

1. Windows Disk Cleanup

Windows comes with a handful of great tools to help keep your computer’s storage nice and tidy. The problem is, not everybody knows where to find these functions, or what to look for.

Disk Cleanup is the first of these tools. It allows you to delete data such as temporary files, which can amount to GB’s (gigabytes) of data over time.

To access the Disk Cleanup function:

1. Go to your Computer window (Start -> Computer)
2. Right-Click your hard-drive and select ‘Properties’
3. Under the ‘General’ tab, click ‘Disk Cleanup’
4. Windows will scan your drive and let you know how much space you can save by running Disk Cleanup
5. Select the files that you wish to delete form the drive, and hit OK

Another function to mention here is ‘Clean up system files’. Using this function, you can remove older Windows restore points from your drive, leaving only the most recent one. If you wish to use this function, please ensure that your computer is running as expected, as once the restore points are removed, you will not be able to fall back to them.

To use ‘Clean up system files’:

1. Click Clean up system files
2. Go to the ‘More Options tab’ in the Disk Cleanup window
3. Click ‘Clean up…’ under the ‘System Restore and Shadow Copies’ heading

2. Uninstall Programs

For many computer users, most of the disk space used is by applications and games. If you find that you no longer use certain programs, you can uninstall and remove them from your hard drive.

Again, Windows provides the ability to easily get rid of any unwanted programs that we may have on our computer. To uninstall/remove programs, follow the steps below:

1. Start -> Control Panel -> Uninstall a program
2. Sort the list of programs by file size by clicking the ‘Size header’. Now you can see which programs take up the most space on your computer.
3. Click any program that you wish to remove, and click ‘Uninstall’

3. Remove Duplicate Files

It is likely that you’ve accumulated duplicate files over time, which are unnecessary for the running of your computer. Unfortunately, Windows does not provide an easy way to find and remove these duplicate files, so a third party software is needed.

There are a number of applications for the removal of duplicate files, but we’ll look at Duplicate Sweeper here. Duplicate Sweeper has a clear and easy interface, and finds and removes duplicates easily.

Let Duplicate Sweeper automatically select duplicate files for removal, using your preferences, or select individual files yourself.

Duplicate Sweeper can find duplicate files, photos and music on your computer, and remove them for you, freeing up loads of space for the stuff you really want.

Try Duplicate Sweeper free ▼

Receive an email with a link so you can download the free trial on your computer:

Note: We respect your privacy. We won’t share your Email address with anyone else, or send you spam.

On a similar point, you can also delete any duplicate tracks in iTunes which can take up a lot of disk space. This function can be found in iTunes -> File -> Library -> Show Duplicate Items. From this list you can delete any duplicate tracks.

However, if you have loads of duplicate files listed, which ones should you delete? To manually go through each track and pick the best may take some time. For this reason, many people use a third-party software to help out.

One such application is Tune Sweeper. Tune Sweeper can quickly search your iTunes library for duplicates, and automatically select which to remove based on preferences such as highest quality, longest duration or latest played.

Tune Sweeper can also tidy up your iTunes library by fixing track information, downloading missing album artwork to tracks, removing missing tracks and loads more.

4. Temporary Files

“Wait, we just removed temporary files using Windows Disk Cleanup”, I hear you say. Yes, we deleted temporary files containing webpages, stored on your hard drive for quick viewing. Unfortunately, the Disk Cleanup method did not include files saved by external apps such as Google Chrome or Mozilla Firefox. There may still be gigabytes worth of cookies, internet history and caches stored on your computer.

You can delete this information directly from your browser, or by using a third-party application.

For example, using Google Chrome, you can open the settings menu (the 3 dots next to the address bar) -> More tools -> Clear Browsing data… From here you can select which data you wish to remove, then click ‘Clear browsing data’.

5. Take out the Trash

Some of these files which we have removed using the above steps may end up being moved to the Recycle Bin. This is a nice safety measure, because if you make a mistake and have removed a file which you now want back, you can easily restore the file from the Recycle Bin.

However, the files in the Recycle Bin are still taking up space on your computer. If you’re sure that you would like to remove the files in your Recycle Bin, you can select files and right-click to delete them, or simply click ‘Empty the Recycle Bin’ to permanently delete all of the files.

6. Store data on External Storage or in the Cloud

All previous methods in this list describe how to delete or remove files from your computer which you may not need. However, what of the files which you wish to keep, such as precious photos, video and music? These media types can accumulate to some serious storage space, but if you no longer have space for them on your PC hard drive, you still have options!

A common method for keeping data safe is to transfer it to external storage. There are 2 platforms for storing your data elsewhere from your main computer: physical storage and cloud storage.

Physical storage comes in many different shapes and sizes, but can most commonly be seen as USB Drives or external hard drives. Transferring data from your PC hard drive to an external hard drive allows you to delete the original files on your PC, while still keeping them safe in storage. Needless to say, this can clear a huge chunk of storage space on your PC.

Cloud Storage allows you to store your files on remote servers, and access them via the internet. There are many different cloud service providers: Apple iCloud and Microsoft OneDrive are only two examples. Most providers offer a certain amount of storage space free, and then give the option to pay monthly for more storage space if you should need it.

Consider also that cloud storage is not immune to duplicate files. Since many cloud services charge for more space, it is crucial to remove duplicate files to save valuable space and save yourself money. Check out our guide on how to manage Google Drive files and remove duplicates.

7. Defragment your Hard Drive

When adding a new file to your computer, a particular portion of your hard drive is allocated to store the file. However, after constantly saving and deleting files, a disk will become ‘fragmented’. This means that there are gaps in your hard drive where subsequent files would not fit, so they are left vacant.

As well as affecting your usable free space on your hard drive, fragmentation also has a negative impact on your computer’s ability to store your data in sequence, hence slowing down it’s speed.

Luckily, Windows has us covered, providing a ‘Disk Defragmentation’ tool. Using this tool, we can analyze which of our drives would benefit from defragmentation, before we commit to defragging. This is very useful, as if you have a large drive full of data, it may take a substantial amount of time to defrag.

To make use of this tool, hit your Windows icon, or Start menu, then start typing “Defragment”. From the search list, click Disk Defragmenter. Once you see the tool’s window, you can elect each drive and analyze them to determine what percentage of them is fragmented. Higher percentages mean higher fragmentation.

To defragment your disk, just hit “Defragment Disk”.

• It is not advised to defragment your hard drive too often, as the constant writing and erasing of data can reduce the lifespan of your hard drive.
• It may also be worth pointing out that there has been some debate as to whether defragmentation of SSDs (solid-state drives) is beneficial or detrimental to the drive. If you are unsure, you can read up on the discussion at PC World.

8. Sufficient RAM

RAM (Random Access Memory) is the hardware in your computer which determines how you store data. RAM stores data or instructions which you use frequently, providing fast read or write processes to improve the general speed of your computer experience.

Sounds great, right? Right. However, if you don’t have sufficient RAM, your computer will start to store the overflow of information which should be stored in RAM, in your hard drive instead. Then, when your computer wants to read or write this data, it is a much slower process between hard drive-computer than RAM-computer.

For these reasons, make sure that you have enough RAM for the processes that you generally do on your computer. It may be worth pointing out that the average user, who’s agenda may be text editing and web browsing, will not require as much RAM as a user who frequently runs multiple programs at once including photo or video editing and rendering software.

You can find out how much RAM you currently have installed in your computer by going to Computer > Properties.
