If you move the Temporary Internet Files folder in Internet Explorer 4.0, cookies are left in the old folder and you do not receive a warning that your cached subscription content is about to be deleted. Both of these issues have been addressed in Internet Explorer 4.01.
For more information about these issues, please see the following article in the Microsoft Knowledge Base:
```
      ARTICLE-ID: Q172949
      TITLE     : How to Change the Location of Temporary Internet Files
```
The default amount of disk space used by the Temporary Internet Files folder (cache) is increased to 3percent of your hard disk. Earlier versions of Internet Explorer use 2 percent of your hard disk for the Temporary Internet Files folder.
NOTE: If you upgrade from Internet Explorer 3.x to Internet Explorer 4.01, your custom cache size settings are not retained, and the cache is set to 3 percent of your hard disk. If you specified custom cache size settings in Internet Explorer 4.0, those settings are preserved when you upgrade to Internet Explorer 4.01.

Internet Explorer 4.01 includes support for Microsoft Active Accessibility (MSAA) version 1.1. In addition, the following new accessibility options are available under Accessibility when you click Internet Options on the View menu in Internet Explorer, and then click the Advanced tab:

    - "Move system caret with focus/selection changes"

      This option specifies whether to move the system caret when the
      focus or selection changes. Some accessibility aids, such as screen
      readers or screen magnifiers, use the system caret to determine
      which area of the screen to read or magnify.

    - "Always expand alt text for images"

      This option specifies whether the image size should expand to fit
      all of the alternate text when the Show Pictures check box is
      cleared.

         permissions are not copied with the file), Internet Explorer 4.01
         provides a new registry value (ForceCopyAclwithFile) so you can
         revert to the Internet Explorer 4.0 default (NTFS file system
         permissions are copied with the file).
