Overview of Junk Files

Before diving into the methods to get rid of junk files, it's essential to understand what junk files are. These files include various system junk files, registry junk files, and other redundant data that serve no purpose. Here are several common types of junk files:

✔ Temporary Files: Created by the system and applications for short-term use.
✔ Cache Files: Stored data to speed up processes but can become outdated.
✔ Recycle Bin Files: Deleted files that are still taking up space.
✔ Old Windows Update Files: Leftover files from previous updates.
✔ Log Files: Records of system and application activities.
✔ Thumbnails: Cached images of your files for quicker previews.

While these files may seem harmless, they can consume valuable storage space, slow down your computer, and even affect its performance. Is it safe to delete junk files? Sure! Regularly cleaning up these files is essential to maintaining an efficient and well-functioning device.

How to Get Rid of Junk Files on Windows 10 PCs?

How can you remove these files and free up storage space effectively? This section offers several common methods to get rid of junk files on your Windows PC. Select the one that best suits your needs.

Method 1. Use Windows Disk Cleanup

Windows Disk Cleanup is a built-in tool designed to help you free up space on your computer by removing unnecessary files. It scans your system for temporary files, system files, and other common junk files.

Here’s how to use it to get rid of junk files on Windows PCs:

Step 1. Right-click on a drive in File Explorer, and click Properties > General > Disk Cleanup.

Step 2. Select the drive you want to clean.

Step 3. Choose the file types you want to delete and click OK.

Step 4. Finally, click Delete Files to confirm and start the cleanup process.

Method 2. Enable Storage Sense

In addition to Disk Cleanup, you can enable Storage Sense to automatically free up space. This tool can delete temporary files, Recycle Bin files, and other unnecessary files. 

Follow these steps to get rid of junk files by enabling Storage Sense:

Step 1. Click Start and select Settings.

Step 2. Go to the System section and select Storage on the left side.

Step 3. Turn on Storage Sense to free up space. And you can customize how often it runs and what it deletes.

If you'd like to clean up files immediately, choose "Configure Storage Sense or run it now".

Method 3. Manually Clearing Browser Cache Files

Browser cache files can speed up processes but may accumulate and take up significant storage space on your device. Here we take Chrome as an example, showing you how to manually clear browser cache files:

Step 1: Open your web browser and click menu.

Step 2: Select Clear Browsing Data from the left-hand side. 

Step 3: On the Delete browsing data dialog, review each information field and check the checkboxes to the left of the information you wish to remove. Then click Delete Data.

Step 4: Close and re-open Chrome to save your changes.
