Microsoft Internet Explorer stores Cookies in different files on your hard disk drive. The more you browse the web, more cookies are stored on your PC. Each cookie has its own lifetime; from several seconds to several years. However, IE does not remove expired cookies from your PC even they are expired and will be never used. Therefore, your hard drive can store several hundreds or even thousands unused and useless files.
So you have to empty the complete cookie folder to delete all the cookies, should you wish to clear disk space. Most do so ! Moreoversome anti-malware consider some cookies as a threat of sorts, and as such remove them. Whether cookies are and overrated threat, is another question.
But if you are like me, who values the cookies, because maybe the help you auto-log in to several of your regular forums or blogs or websites, or preserve your preferred personalized settings, then you may not want to lose such cookies.
You may want to only delete the expired cookies or optimize them. What does optimize mean? Cookies are stored in files. One file may contain more than one cookie. If only several cookies (not all) in this file are expired, then these cookies are deleted, from a file and reported as optimized.
