A real controversy

The Internet privacy group consider the use of index.dat on Windows operating systems are an invasion of privacy. The information contained in these may be private to the user. One of the complaints held is that the file can not be removed easily. This is because Windows prevents locked files from being deleted.

While some claim that the Windows OS deliberately hidden index.dat files, others point to the fact that Windows Explorer offers a detailed view of the contents of the files when the content folders is scanned, even allowing for the removal of specific entries.

Some free programs can completely remove index.dat files until it is re-created by Windows. These programs do not eliminate the index.dat file in the folder of temporary Internet files containing a copy of the cookies.
