OpenExpert. Manage your Windows file associations with this dinky program. Free for personal use.
OpenExpert enables you to specify any number of suitable applications for each file type. In this way, when you open a file, instead of being restricted to using a single pre-determined application, you can easily choose among a list of suitable applications. Easily open your graphic files in your favorite paint programs or view your HTML files in either Netscape or Internet Explorer, just with a few mouse clicks. You can even add different versions of the same program to the OpenExpert menu.
