Choosing which cookies to keep

A cookie is a small file that a Web site can place on your hard drive. It contains information about when you visited the site, and may contain tracking and settings information. For more information about cookies, see the Wikipedia entry.

Note: Flash cookies (which are used by Adobe Flash) are cleaned differently by CCleaner. See this topic for more information on Flash cookies.

You may choose to delete cookies for privacy reasons. Be aware, though, that some sites may forget your login data if you delete their cookies. Others will simply replace the cookie the next time you visit.

By default, when you run the Cleaner, CCleaner deletes all of the cookies for all of your Web browsers (Internet Explorer, Mozilla Firefox, Safari, Opera, and so on). There are two ways to keep cookies on your PC while still making full use of CCleaner.

Option 1: To keep all cookies on your PC

  1. In CCleaner, click the Cleaner icon on the left.
  2. On the Windows tab, under Internet Explorer, clear the Cookies check box.
  3. If you have no other Web browsers installed, you have finished. If not, click the Applications tab.
  4. Under each browser listed, clear the Cookies check box.

From this point on, whenever you run the Cleaner, it will retain all cookies from these browsers.

Option 2: To keep certain cookies on your PC

  1. In CCleaner, click the Options icon on the left.
  2. Click the Cookies button. The list may take a few seconds to load. This list displays cookies from all the browsers you have installed on your system.
  3. By default, all cookies are in the Cookies to Delete column. To keep cookies, move them to the Cookies to Keep column by selecting cookies and clicking the right-arrow button. You can select multiple cookies by using CTRL+click, or select a set of cookies in a row by clicking the first one and then SHIFT-clicking the last one.

Option 3: To use Intelligent Cookie Scan

  1. In CCleaner, click the Options icon on the left.
  2. Click the Cookies button. The list may take a few seconds to load. This list displays cookies from all the browsers you have installed on your system.

  4. Dialog box Intelligent Cookie Scan will appear and ask you to allow CCleaner to keep your persistent logins for websites.

Notes:

  • If you use the method in Option 1 to keep all cookies on your PC, the cookies in the Cookies to Delete column will not be deleted.
  • If you have a long list of cookies, you can easily search through them for the ones you want. Click inside the Search box and type a few letters in the cookie's domain name. For example, typing HOO will return cookies for Yahoo.com.
  • If you want to add an domain entry that hasn't appeared on your PC yet, right-click a blank part of the Cookies to Keep list, and then click Add. Type the domain name in the dialog box and then click OK.
