Users Cookies are among the least understood aspects of using the Internet. Cookies have been accused of everything from spreading viruses to sending personal information without a person's consent.
Cookies are small text files that a Web server places on the hard disk of the client computer.
The fact that a Web server can write to a user's hard disk is the source of much concern about cookies. Many users feel that if a Web server can write to their hard disks, the server can do other things as well, such as deleting files. This is one of the many myths about cookies. A common type of cookie is the persistent cookie, so-called because these cookies have no expiration date and remain on a computer's hard disk indefinitely. Depending on which version and browser you use, you can simply delete the cookie files from the directory in which they are stored, or you can use the Delete Files button in the Temporary Internet Files area of the Internet Options dialog box.
