For those who are very familiar of Ccleaner, it's a free utility software that clears all unnecessary junk files to free up hard disk space, especially cache files or temporary internet files. Windows users have it very easy because they have Ccleaner. The purpose of course is to make our Mac work smoothly and efficiently.
