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:

Added download link for Ccleaner 5.0 Beta:

CCleaner v5.0 sees a change with a redesigned, modern interface. The current interface you know and love has remained largely the same since its first release almost 10 years ago, so we decided it was time to give it a fresh new look!

Our design team have worked hard to bring CCleaner up-to-date while making sure it still felt like the same tool that our hundreds of millions of users love. We are extremely happy with the result, and we hope you are too!
