Description :
CCleaner is a utility for cleaning garbage in the operating system. During its work, CCleaner (Crap Cleaner) searches for and deletes temporary and unused files. This includes: cookies, site history in IE, temporary Internet files, search strings, Trash files, etc. It also supports searching for temporary files of third-party applications: Firefox, Opera, Media Player, eMule, Kazaa, Google Toolbar, Netscape, Office XP, Nero, Alcohol 120, Adobe Acrobat, WinRAR, WinAce, WinZip, GetRight, Morpheus, Download Accelerator Plus, VirtualDub , ZoneAlarm and many others. You can also clean the Windows registry, ridding it of unnecessary extensions, old dlls and incorrect paths that accumulate in considerable quantities, especially after installing and uninstalling various programs. By doing all these operations on your system, you will not only free up disk space, but also increase the performance of the system as a whole.
