Duplicate File Finder

You may not realize how many duplicate files are stored on your computer, taking up valuable hard drive space. CCleaner now includes a duplicate file finder tool, which can quickly find these files, and allow you to choose which ones to delete - freeing up more space on your PC than ever before!

System and Browser Monitoring

If you're a CCleaner Professional user, you can now set CCleaner to run every time you shut down your browser, or you can set it to monitor your entire system in the background and detect when to Clean based on disk space that can be saved!

What's New

With CCleaner v6.30, we've launched Cloud Drive Cleaner out of Beta, now supporting Microsoft OneDrive. We've also enhanced Software Updater and optimized our app's browser cleaning capabilities.

Taking the hassle out of PC maintenance

  • We've now made our Cloud Drive Cleaner work with both Microsoft OneDrive (new) and Google Drive for all paid users.
  • We've upgraded our Software Updater library to offer you more app updates than ever.
  • For Software Updater, we've also tweaked it so that it now cleans up installers downloaded during the updating process more effectively.
  • We've improved how our app cleans Opera and other Chromium browsers, including cache files and saved form-fill data.
  • We've done various UI improvements, including localization fixes and adding links to the knowledge base in Software Updater, Performance Optimizer, Duplicate Finder, and license activation. This is to help improve how you experience our app and to make it easier for us to resolve issues.

Fixing bugs and other improvements

  • In Software Updater, we've now made the "update complete dialog" appear correctly. This is once all the programs in Software Updater update completely. Previously, it would appear too early while updates were still going on.
  • In Driver Updater, we've fixed the issue causing some drivers to display the wrong installation dates.
  • We resolved the issue causing the CCleaner update to fail for some users once they clicked on the pop-up notifying them about the latest version of our app.
  • In Health Check, we've corrected the issue that stopped users from canceling software updates they've already asked for.
