SearchFilterView is a freeware tool to get the list of search filters in your Windows. This utility allows you to easily view the search filters installed on your system and the file extensions that are associated with them, as well as it allows you to easily add or remove file extensions for these filters.
The application does not require any installation, you can directly run the exe file and it lists out all the filters in Windows.
