Программа для удаления с жесткого диска ненужных данных - временных и лог-файлов, кукисов и других файлов, находящихся в кэше браузера, и т.п. System Cleaner "понимает" более ста расширений, используемых для обозначения временных файлов, позволяя тем самым автоматизировать процесс очистки жесткого диска от накапаливающегося со временем хлама; дефрагментация и очистка реестра; с другой стороны, возможен поиск (и удаление) файлов с любыми другими расширениями. Кроме этого, программа допускает удаление неправильных записей из апплета "Установка и удаление программ". Немаловажно, что System Cleaner позволяет производить не просто удаление файлов, но их надежное удаление - без возможности последующего восстановления какими-либо утилитами.

System Cleaner™ is a tool for restoring hard-drive space, cleaning up the history of your activities on your computer and keeping your system running like new. The program allows you to clean your drives from unnecessary and temporary files, including your browser cache, cookies, history, recent document list, temporary files, errant uninstall entries and more. It targets more than 100 file extensions, which enable it to scan and recognize most of the unnecessary files on your computer. You can choose to delete the files to the recycle bin or to a specified backup folder.
