RF Types

There are countless file formats, even more for a single purpose. Differences are because of quality and builder configurations. Needless to say that there are more ways to open a single type of file by default. In case you want to analyze extensions and associated programs, then you can rely on RF Types to get the job done.

It’s recommended to install and run the application with administrator privileges so it can properly access system registry entries to read all file extensions. Accommodation doesn’t really take more than a couple of minutes thanks to the organized layout of info fields, as well as functions you can perform.

As soon as the application starts it scans your computer to read all registered extensions as well as their associated program. This operation takes little time, and all entries are displayed as detected in a large table with column headers for extension, file type, whether or not it’s inside the Open With context menu entry, and the registry location.

Hovering the cursor over elements provides a detailed view, including key value, context type MIME, default icon file, default action, as well as a table of actions and commands which are triggered when the file is opened. Additional information can be accessed to view aforementioned details in a better window.

Note that the application is only a viewer, and doesn’t let you manage anything. On the one hand, this prevents you from making any mistakes, while on the other hand, keeps you from changing a file association. You can load and save registry configurations, or export reports of various file formats with gathered information.

Taking everything into consideration, we can state that RF Types comes as a cool application if you wish to get an idea of what registered extensions exist on your computer, and what applications are used to open them. Even though you can’t edit anything, it’s surely worth the effort, providing thorough details.
