Temporary Internet Files are files that are stored on your computer each time you visit a web site. These files help reduce load times of frequently visited web sites by placing a copy of the site on your computer. The problem with the temporary files is that the copy on your computer may take priority when loading the site. This means your view of the web site may not be current. Temporary Internet Files accumulate over time and may take up large portions of disk space.
Cookies are small files placed on your computer by web sites so that a site may remember your settings. Deleting these files will reset your saved options of those sites to default, which could be causing problems.
