Investigating Prefetch Files
Another awesome utility from Nils Sofer at Nirsoft. This application allows you to dig into prefetch files that are created on your system to aid in speeding up the cold boot time of an application. The following is taken directly from Nirsoft’s blog.
Each time that you run an application in your system, a Prefetch file (.pf file) which contains information about the files loaded by the application, is created by Windows operating system. The information in the Prefetch file is used for optimizing the loading time of the application in the next time that you run it. These Prefetch files are stored in C:\Windows\Prefetch, starting from Windows XP.
WinPrefetchView is a new utility that allows you to easily watch the content of these .pf files. By looking in these files, you can learn which files every application is using, and which files are loaded on Windows boot.
