This is the most useful software after MS Word in recent times. It’s actually used to clean internet browser caches, junk files, cookies which releases the security issue. It’s actually cleaned the unwanted junks which can be threaten for our safe & secure browsing. It also clean junk files, recent files of Operating System from hard drive which reduces the risk of HDD crash.
From my personal experience the only Cons is Sometimes it used to delete the original file from HDD but it’s not happen in all times.
