The sections and items that show up in CCleaner's Applications tab depend on which applications you have installed on your Windows PC.
If an application or type of application has many features (for example, with Firefox you can delete cookies, clear the download history, and so on), that application will have its own section, and you can select specific areas you want to clean.
If an application is simply listed in the Applications, Internet, Multimedia, Utilities, or Windows sections with no details, the cleaning process will typically clear out document history (MRUs), visited URLs, and temporary files for that application.
Web Browsers (for example, Mozilla Firefox, Google Chrome and Safari)
- Cookies - Web cookies stored by each browser. Note that the cookie list in the Options section of CCleaner controls cookies for all browsers you have installed, not just Internet Explorer. For a further discussion of cookies, please see the Choosing which cookies to keep topic.
- Download History - A list of files you downloaded through that browser.
- Session – You can save the session and reopen it at the later time. Session contains all saved and opened tabs.
- Internet Cache - HTML, images, and other files accumulated while you surfed the Web using that browser.
- Internet History - A list of the sites you visited and the dates on which you visited them.
- Saved Form Information - User names, passwords, search terms, and anything else you typed into any forms that appeared in the browser's HTML canvas.
- Compact Databases - Some Web browsers (notably Mozilla Firefox and Google Chrome) use databases to store bookmarks, history, and other data. When you remove information from these databases, they may still take up room with fragmented space. If you select Compact Database, CCleaner will defragment and trim unused space from these databases.
- Website Icons – Some browsers store website icons which are displayed on the address bar and in the favorites list.
- Saved Passwords - Web browsers can store passwords for pages you've visited.
Other applications and utilities
- Applications - These refer to third-party applications you've installed that don't fall under the Internet, Multimedia, or Utilities category. Some examples are CD/DVD-burning programs and word processing software.
- Internet - These programs include browser add-ons such as Flash and the Google toolbar, instant messaging programs, and firewalls.
- Multimedia - These programs are video players and editors, or video helper programs for Web browsers.
- Utilities - These include utilities such as Zip management, disk tools, and spyware scanners.
- Windows - Some of Windows' own applications contain lists of recently-used documents. Examples are Paint and Wordpad.
Note: An asterisk (*) next to an application's name means that you (or a system administrator) have added it to CCleaner as a custom application.
