Method 1: Check What Is Taking Up Disk Space in Windows 11 & Free Up Safely

Storage Settings is the primary Windows 11 tool for understanding disk usage. We use this approach when we want a clear breakdown before deleting anything. In this system, you will be able to see the categories like Apps, System, Temporary files, and Other. Always check first, then clean only recommended sections. So, How to see what’s taking up space on PC Windows 11? 

To check disk space usage and remove the heavy file safely, follow these steps- 

1. Open Settings using Windows + I → click System → select Storage.

2. Wait for Windows to calculate space usage by category such as Apps, System, Temporary files, and Other.

3. Open Temporary files, review each item, then select safe options like Recycle Bin or Temporary Windows files and click Remove files.

Note:

• Do not delete files from the System category manually.
• Always review Downloads before cleaning

Method 2: Use Storage Sense to Automatically Free Up Space

Storage Sense reports provide automatic tracking of disk usage trends. Use this method if Storage Sense is enabled. It highlights areas where space is frequently consumed. Review reports before enabling auto-cleanup.

Steps:

1. Open Settings > System > Storage.
2. Click Storage Sense.
3. Review usage history for Temporary files, Apps, and Cloud content.
4. Identify recurring space usage patterns before cleaning.

Note:

• Storage Sense does not delete personal files automatically.
• Cloud-only files can be re-downloaded anytime.

Method 3: Delete Temporary Files Safely

Windows Temporary Files are short-term files created by the operating system and apps to store temporary data. Windows Temporary Files are usually safe to delete when your PC feels slow or storage is running low. For example, after installing software or using apps heavily, these files may remain unused and take up space.

Steps:

1. Press Windows + R on your keyboard to open the Run dialog box. Then, type %temp% and click OK.

2. A File Explorer window will open showing temporary files. Press Ctrl + A to select all files and folders in this window.

3. Right-click on the selected files and click Delete. If a message appears saying some files are in use, click Skip.

4. Close File Explorer and empty the Recycle Bin to free up space completely.

Note:

• Some files cannot be deleted because they are currently in use
• Skipping files is safe and will not harm Windows

Method 4: Update Cache

Update Cache stores downloaded Windows update files before installation. Update Cache is useful during updates but can be deleted after updates are completed. For example, if Windows Update finished successfully, old cache files may still remain and occupy disk space.

The steps are the same as method-1. To see the image tutorial, please check the method-1 above.

1. Press Windows + I to open Settings.
2. Go to System → Storage.
3. Click on Temporary files under Storage. Wait while Windows scans for removable files.
4. Check the box labeled Windows Update Cleanup. Review other checked items carefully before proceeding.
5. Click Remove files to delete the update cache safely.

Note:

• Only delete update cache after updates are installed. 
• Do not interrupt the removal process.

Delivery Optimization Files

The delivery Optimization Files are used by Windows to share update data with other PCs. Delivery Optimization Files can grow large over time and are safe to remove when storage is low. For example, if you do not share updates across devices, these files are unnecessary.

Steps:
1. Open Settings using Windows + I.
2. Go to System → Storage.
3. Click Temporary files from the list. Allow Windows to calculate storage usage.
4. Select Delivery Optimization Files by checking the box. Make sure no important items are selected accidentally.

Method 7: Clean Browser Cache and App Data

Clean Browser Cache and App Data is a method that removes temporary internet files and stored app data from your system. It is used when browsers feel slow or storage fills up unexpectedly. This method works because cached images, videos, and offline data can grow very large. For example, frequent YouTube streaming or heavy browsing can create gigabytes of cache files.

1. Open Google Chrome on your Windows 11 PC. Click the three-dot menu in the top-right corner and select Settings.
2. In the left sidebar, click Privacy and security. Select Clear browsing data from the main panel.
3. In the pop-up window, choose the Time range as All time. Check Cached images and files and uncheck Passwords if you want to keep them.

6. Click on an app such as Microsoft Edge, Spotify, or Teams. Select Advanced options, then click Repair or Reset if cache size is high.
7. Restart your PC to ensure freed space is fully reflected in storage. Check disk space from this PC to confirm improvements.

Note:

• Clearing cache may sign you out of some websites.
• Do not clear saved passwords unless backed up.
• App reset removes local data but keeps the app installed.
• Cache will rebuild automatically over time. 

What NOT to Delete on Windows 11

Freeing up disk space on Windows 11 is helpful, but deleting the wrong files can cause serious problems. Some files are essential for Windows to run properly. Before cleaning your PC, it is important to know what not to delete and why. Let’s check- 

• C:\Windows folder: This folder contains core Windows system files. Deleting it can make Windows unbootable.
• Program Files / Program Files (x86): These folders store installed applications. Removing files manually can break apps and cause errors.
• System32 folder: This folder holds critical system drivers and DLL files. Deleting anything here can crash Windows.
• WinSxS folder: It supports Windows updates and system recovery. Deleting it manually can prevent updates or rollbacks.
• System Volume Information: This folder stores restore points and backup data. Deleting it removes recovery options.
• Drivers (.sys files): Driver files control hardware like Wi-Fi, sound, and display. Removing them can disable devices.
• AppData folder (without checking): It contains app settings and user data. Deleting it can cause apps to stop working or lose data.
• Documents, Pictures, Desktop folders: These folders often contain personal or work files. Deleting them can cause permanent data loss.
• Downloads folder (without review): Some files may still be needed, such as installers or important documents.
• Recovery or EFI partitions: These are required to repair or reset Windows. Deleting them can prevent system recovery.

Simple rule to remember: If you are not sure what a file is or Windows does not suggest deleting it, do not delete it manually.

How Much Free Disk Space Windows 11 Needs

Windows 11 works best with at least 20–25 GB of free disk space. Microsoft requires 64 GB total storage, but real-world use needs extra free space for updates and smooth performance.

On an SSD, low free space quickly reduces speed and lifespan, so keeping 25–30% free space is ideal. On an HDD, performance drops with low space too, but the impact is slower compared to SSDs.

When free space is low, Windows updates may fail, apps open slower, virtual memory struggles, and the system can freeze or lag. For best performance, always keep 20–30 GB free on your Windows 11 system drive.

When Freeing Disk Space Is Not Enough

Sometimes clearing files does not fix slow performance or storage warnings in Windows 11. In these cases, the problem is usually not just disk space. 

The drive is almost full again quickly. This often means large apps, games, or sync tools like cloud storage are using space continuously. If your PC has a 64 GB or 128 GB drive, cleanup helps only temporarily. The drive size itself is the limitation. On HDD-based systems, even with free space, Windows 11 can feel slow due to hardware limits.

When RAM is low, Windows uses disk space as virtual memory, causing slowdowns even after cleanup. Apps running in the background consume resources and reduce overall system performance. Update files, restore points, and system caches can quickly refill freed space.
