Notes about the IEPK file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries, unused processes and other unfavourable system settings to identify slowdown issues.
The IEPK file type is primarily associated with 'IE Privacy Keeper' by BrowserTools.net. Whether you are using Internet Explorer or Mozilla Firefox, IE Privacy Keeper automatically cleans up the browser history once you are done surfing the net. The program will correctly clean up all index.dat files without the need for a Windows restart.
