Running out of disk space on your Windows 11 computer can be frustrating. It slows down your system and makes it hard to save files or install new programs. The good news is that you don’t have to delete important files or software you rely on. Here are easy and safe ways to check the biggest system files on Windows 11 and free up space on your PC.

1. Start with Storage Settings

  2. Navigate to SystemStorage.
  3. You’ll see a breakdown of what’s using your disk space, such as Apps, Features, and Temporary Files.

Enable Storage Sense

Storage Sense is a built-in Windows tool that automatically cleans up temporary files, empties the Recycle Bin, and removes old files from your Downloads folder.

  1. In the Storage menu, toggle Storage Sense to “On.”
  2. Click Configure Storage Sense to customize its settings. You can choose how often it runs (daily, weekly, or monthly) and decide what types of files it should remove.

Tip: If you’re worried about accidentally deleting files from your Downloads folder, adjust the settings to ignore it or remove files only after a specific number of days.

2. Use Disk Cleanup for a Quick Fix

Windows includes a handy tool called Disk Cleanup that helps remove temporary and system files:

  2. Select the drive you want to clean (usually C:).

Clean System Files

  2. Confirm your choices and click OK to proceed.

Tip: To ensure all system-level junk files are removed, run Disk Cleanup with administrator privileges.

3. Find and Remove Large Files

Even after using Storage Sense and Disk Cleanup, large files might still be taking up space. These could include video files, old ISO images, or system files like pagefile.sys and hiberfil.sys.

How to Find Large Files on Windows 11

Using File Explorer
  1. Open File Explorer and select This PC.
  2. In the search bar, type size:>1GB (or size:>500MB) to search for large files.
  3. Wait for the results to load. This method lets you find large files on disk in Windows 11.
Using Third-Party Tools

Tools like WinDirStat or TreeSize Free provide a visual way to locate large files on your disk. These tools are especially helpful if you want to search for the largest files on your PC in Windows 11.

What to Do After Finding Large Files

  1. Move unnecessary large files to an external drive or cloud storage.
  2. Delete files you no longer need, but double-check their importance first.

Tip: Avoid deleting system files unless you’re sure they aren’t essential.

4. Uninstall Unused Software

Old or rarely used programs can use up a lot of space. Here’s how to remove them:

Go to Apps & Features

  1. Press Windows key + IAppsApps & Features.
  2. Sort the list by Size to find the largest programs.

Uninstall Programs

  1. Select the app you don’t need and click Uninstall.
  2. Follow the prompts to complete the process.

Tip: Look up any unfamiliar programs before uninstalling them. Some may be essential drivers or utilities.

5. Clear Browser Cache and Temporary Data

Web browsers store cached files, cookies, and other data that can take up space. Here’s how to clear it:

Chrome

  2. Select Cached images and files and any other data you want to remove.

Firefox

Cloud storage tools like OneDrive, Google Drive, or Dropbox can sync unnecessary files to your PC.

Selective Sync

  1. Open your cloud storage app’s settings.
  2. Choose which folders to sync to your computer.
  3. Use features like OneDrive’s Files On-Demand to keep files online until you need them.

7. Empty the Recycle Bin

The Recycle Bin stores deleted items until you empty it. If you’re sure you don’t need these files:

  1. Right-click the Recycle Bin.
  2. Click Empty Recycle Bin and confirm.

Tip: Double-check for any important files before emptying the bin.

8. Advanced: Disable or Reduce Hibernation

Windows creates a file called hiberfil.sys to save the system state during hibernation. If you rarely use this feature, you can disable it to save space.

Disable Hibernation

  1. Open the Command Prompt with administrator privileges (search for “Command Prompt” and select “Run as Administrator”).
  2. Type powercfg /hibernate off and press Enter.

Re-enable Hibernation

  1. If you want it back later, type powercfg /hibernate on and press Enter.

Note: Disabling hibernation means you can’t save the system state to disk. Only disable it if you don’t rely on this feature.
