Step 3: Selecting Disk Cleanup Options

1. After selecting the drive, Disk Cleanup will analyze your selected drive to determine the types of files you can delete.

   • Temporary Internet Files: This includes website images, cached pages, and other temporary internet files.
   • System error memory dump files: These are files that store information about system crashes. You can safely delete them if your system is stable.

   • Thumbnails: This includes cached thumbnail images for quicker file browsing.
   • Windows Update Cleanup: This removes old Windows update files.

   Note: Be cautious when selecting options and ensure you don't delete anything important.

3. Once you have selected the desired categories, click the OK button to start the cleanup process.

Step 4: Confirmation and Cleanup
