Dedaulus System Cleaner (DSC) is the small utility, not needed to install, that helps you to clean your PC from various garbage.
DSC allows to clean temp folders and cache/history/cookies of Web browsers (Internet Explorer, Opera 8-9, Firefox 1.5+). DSC also allows to organize search of temporary files of other programs, using special masks (you can edit them at own discretion), search of bad shortcuts, search of empty folders, search of duplicates, and search of registry errors.
