How to clean your system and free disk space with BleachBit

BleachBit allows you to quickly free up disk space and guard your privacy by securely erasing cache, cookies, and hidden temporary files. Follow these steps to get started:

  1. Launch the Software
    Download the open-source setup for Windows or Linux and install it. Open the BleachBit application (Run as Administrator for deep system cleaning) to begin.
  2. Select Items to Clean
    On the left panel, check the boxes next to the applications or system areas you want to clean, such as Google Chrome cookies, System Logs, or Windows Explorer temporary files.
  3. Preview Your Savings
    Click the Preview button at the top. The tool will scan your system and display a detailed list of exactly which files will be deleted and how much total disk space you will recover.
  4. Clean and Shred
    Once you are satisfied with the preview, click the Clean button. BleachBit will permanently erase the selected junk files. You can also use the File menu to shred specific files or wipe free disk space.
Pro Tip: Beyond simple deletion, use the "Wipe Free Space" feature to securely overwrite traces of files that were previously deleted by other applications, ensuring they can never be recovered!
