About CCleaner

CCleaner has two main uses. One, it scans and deletes useless files, freeing up space. Two, it deletes private data like your browsing history and the list of the most recently opened files in various programs. In a way, it's kind of like Windows' built-in disk cleanup tool, which frees up space on your hard drive by deleting useless files: old temporary files created by programs, temporary Internet files for Internet Explorer, error reporting logs Windows and more. You can run this tool at any time to free up disk space.

CCleaner does these things and more. It takes the Disk Cleanup concept and runs with it, extending it to more data in Windows and third-party programs than the Windows Disk Cleanup tool won't touch. For example, it will clear cache files for other browsers like Chrome and Firefox, or remove useless configuration folders that NVIDIA graphics driver installers create when updating their graphics drivers, which can consume hundreds of megabytes each.

Just select the types of data you want to delete, click the Analyze button and look at the data that CCleaner will delete. If you are satisfied, click the Run Cleaner button to actually delete the selected files. CCleaner will remember your choices for next time, so you can open it and click the Run Cleaner button in the future.

CCleaner also deletes private data

CCleaner has another purpose: it will also delete data for private use. For example, CCleaner will erase your browser history, cookies, and cache files from any browser you have installed: Internet Explorer, Firefox, Chrome, and even Opera. It will go beyond that, deleting the cookie data stored by Flash Player. It will even remove other potentially dangerous data for privacy, like the list of recently opened file names in Microsoft Word, Adobe Reader, Windows Media Player, VLC media player and other common Windows applications.

This is all customizable, but CCleaner is set to clear this data by default. CCleaner not only quickly deletes useless temporary files, it's like some sort of "Delete My History" function on the whole computer that deletes more than just your browsing data. Of course, CCleaner doesn't know all the programs you can use, so this will never be perfect. Cache files are parts of web pages (images, scripts, style sheets, HTML files, and more) that your browser preserves. For example, when you visit a site, your browser downloads the site logo that we show at the top of the page. Then save this logo in your cache. When you navigate to a different page on our website, your browser does not have to download the logo image again, it just loads the image from the browser's local cache. Your web browser is constantly doing this with different parts of web pages, and speeds up the loading of the web page because your browser doesn't have to download the same files over and over again. In addition to its disk cleaner, CCleaner contains some other tools as well. Some, like its ability to create a list of installed programs. It also contains an uninstaller, a startup manager and an interface for System Restore.
