What Is a Cookie File or Folder?

Cookie files are how your browser stores website cookies. Here's what you should know about them.

Cookies are small, usually randomly encoded, text files that help your browser navigate through a particular website. 

A cookie file is generated by the site you're browsing and is accepted and processed by your computer's browser software. Once accepted, the cookie file is stored in your browser's folder or subfolder.

How does your browser use cookie files?

Your browser accesses the cookie file again when you visit the same website that created the cookie file. 

Your browser uses the information stored in the cookie file to remember any settings you selected during your earlier visits to the website or to remember other information, like your login credentials.

No website can access information on your computer other than the cookie it saved to your computer.

Are cookie files dangerous?

Cookies aren't executable code, so they don't pose any direct threat to your computer. And a website's use of cookies is limited to helping your browser process the information located on the website.

Although cookies are merely harmless text files that help your browsing experience, they aren't free from controversy. Cookies can also be used to track your browser's website browsing history.

If you feel this impacts your privacy, you can change your browser's settings to limit the use of cookies on your computer to cut down on its ability to keep records of your browsing history.
