CCleaner is a software tool used to improve the computer’s speed and performance by removing all the unnecessary files within it. It is made by Piriform which has been acquired by Avast, a security software, back in 2017. It is known as an efficient system cleaner that is used for both Microsoft Windows and Mac computers.
What is CCleaner?
CCleaner can be used for system optimization, a better computer performance, and for additional privacy. It cleans out all the files that are unused and unnecessary for your computer. By doing this, your hard disk space is freed for more files to be downloaded inside. It also has a registry cleaner.
The following can be cleaned by CCleaner:
- Internet browsers– The current browser that you use can keep track of the different websites that you visit through the History function. It can also keep cookies from the websites you visit for them to recognize you once you visit them again. Other information stored by browsers include Autocomplete from History (passwords and email addresses) and indexing files. Browsers such as Internet Explorer, Firefox, Google Chrome, Opera, and Safari will keep track of all these automatically unless you disable them through the Settings tool. CCleaner can clean all these files. Other browsers supported by CCleaner include Google Chrome Canary, Flock, Rockmelt, K-Meleon, SeaMonkey, Chromium, Chrome Plus, Phoenix, SRWare Iron, Pale Moon, Netscape Navigator, and Avant.
- Windows System Files– There are also a lot of junk items within your Windows operating system that may be unnecessary. These are created from recent documents and files that you have deleted or have moved out of your system. Some of these junk files include those in the recycle bin, temporary files, recent documents, clipboard, log files, DNS cache, memory dumps, jump lists, and error reporting. CCleaner makes sure that only those that are not crucial for your day-to-day operations will be deleted.
- Registry Files– The registry keeps track of all of the applications in your computer. Whenever you uninstall an application, it may not fully delete itself from your system and take up space in your registry and cause a slower computer performance. CCleaner can clean file extensions, ClassIDs, Uninstallers, Shared DLLS, ActiveX Controls, ClassIDs, Help Files, Application Paths, Invalid Shortcuts from your registry.
- Unnecessary third-party applications– You may download additional applications along with others when you’re not paying attention, whenever they come in bundles. CCleaner can be used to delete these along with recent files and temp files. Some applications that it can delete include Microsoft Office, Google Toolbar, eMule, Windows Media Player, Adobe Acrobat, Nero, WinZip, WinRAR, and WinACE (with the user’s permission).
CCleaner’s main priority is deleting from your computer files that are not necessary. Most of these are junk files, leftovers from uninstalled ones, which take up space but are unused. This improves the performance of your computer by reducing the system junk. It also widens the space for more applications to be downloaded.
CCleaner is also certified to be safe for your computer. It does not take any of your files and is not a malware or virus file.
