Clearing Space on Windows 10

Windows 10 is great in showing you how much storage space you have, breaking it down into sections, and offering quick steps to actually free up the disk. To begin, press Windows key + I to launch Settings, then click System, and select Storage from the left menu.

This screen will show you what storage devices you have attached, both internal and external, along with the default storage locations for things like new apps and documents. Though it won’t initially free up space, it’s worth looking at the Save locations section if you have multiple drives. For example, if you’ve got an external drive with loads of available space, then you might want to consider storing new music and videos to it – use the drop-down menus on each section to make the change.

When ready, click a drive beneath the Storage header to see what is occupying the space. The icon with the Windows logo on it designates that your operating system is installed to that drive. If this is your first time accessing the Storage usage breakdown for the drive, then you might have to wait a short period while it calculates everything. To update the analysis, click the circular arrow at the top.

You’ll be presented with a list of everything on your drive, broken down into specific categories. Each category has has its own colored bar to show usage amount, which is then amalgamated into the bar at the top, giving you a quick glance at which sections are taking up the most amount of space. Let’s go through each in turn to explore the options. Firstly, click System and reserved.


System and Reserved

Of these, System files and Virtual memory aren’t alterable. Third on the list is Hibernation file, which takes up around 6GB of space (dependent on your system memory).

This window allows you to adjust how much of your drive space you want to allocate to the system restore function. The more space you allow, the more restore points will be available. As new ones are created, the older ones will be deleted to free up space. Adjust the slider to change the percentage of your drive that you want to allocate to system restore.


You can click Delete if you want to remove all restore points for the drive. You can also click Disable system protection to turn off the feature altogether. However, neither of these options are particularly advisable, unless you have another recovery solution in place. There’s no point risking data loss for the benefit of some storage space.

Apps and Games

Navigating back to the storage usage screen, the next category to select is Apps and games. This will list all of the programs installed to your system. By default, the list will be sorted by size, but you can use the dropdown to sort by name or installation date instead. You can also search for a specific app and switch between drives.

Typically, you’ll find that games will dominate the upper half of the list, simply because they pack in a lot more data than a program. The file size of games continues to increase, with recent releases like Titanfall, Batman: Arkham Knight and Grand Theft Auto V all taking up around 50GB or more of hard drive space. If you’re a big gamer, it’s easy to see how quickly a hard drive can get full.

If there are any apps or games that you don’t use any more, you should remove them to free up space. To do so, simply click it on the list and then select Uninstall. You can also click Manage optional features at the top, where you can uninstall things like additional language packs.

If you want to see the more traditional presentation of this list, which in my opinion presents the information in an easier to read way, do a system search for programs and features and select the relevant result.

Documents, Pictures, Music, and More

Many of the categories on the storage usage page relate to personal data. These are Documents, Pictures, Music, Videos, Mail, OneDrive, Desktop, and Maps. Clicking into these sections will then let you navigate to the folder on your system where the relevant data is stored.

It’s not up to Windows or this guide to dictate what personal data you should remove, but you could sort your folders by creation date to see if there’s anything old that you don’t use anymore. Alternatively, you could consider archiving data to an external drive – that way you’re not removing it permanently, but it’s not clogging up your main drive.

Temporary Files

The Temporary files section will let you clear out your temporary system files, your downloads folder, and your Recycle Bin. Make sure there’s nothing you want to keep in your downloads or Recycle Bin, but generally speaking it’s safe to clear up these three sections. Just click on the corresponding button to begin the process or navigate to the folder containing the data.
