12 best ways to free up hard drive space on Windows 10

Source: Windows Central

Windows 10 includes several options to free up space when the hard drive on your device fills up. Although drives with multiple terabytes are common on laptops and desktop computers, it does not take a long time to stuff them up with documents, pictures, videos, apps, and games. And then, without warning, you will start noticing slow performance, problems saving files and many other issues.

If your device is running low on space, Windows 10 offers several tools (such as Storage Sense, OneDrive File On-demand, Compact OS, NTFS compression, and many others) to delete junk and temporary files, apps, and games to optimize the device storage. Using these tools will help you reclaim additional space, but it will improve the overall performance and problems during updates.

In this Windows 10 guide, we’ll walk you through the best tips to free up storage space on your device to make room to store more files and install feature updates without issues.

1. Free up space emptying Recycle Bin on Windows 10

On Windows 10, when deleting files, the system does not erase them from the hard drive. Instead, they are placed inside the Recycle Bin in case you need them back. However, depending on how the feature is configured, over time, the Recycle Bin can take a lot of space, which means that emptying the bin is one of the first actions you should take to regain valuable storage space.

To empty the Recycle Bin to free up 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), and then type Recycle Bin and press Enter in the address bar.

Click the Empty Recycle Bin button.

Click the Yes button.

Once you complete the steps, the system will free up around ten percent of the drive capacity (assuming the Recycle Bin is at capacity).

2. Free up space deleting junk files using Storage Sense on Windows 10

On Windows 10, Storage Sense is a feature that allows you to quickly delete junk files (including previous installation files after an upgrade and temporary files) to free up space on the primary and secondary drives to make room to store other files and improve drive efficiency.
