7. Step You probably already have a few default programs that are assigned correctly, you should then use the option “Use my current xxx program”
If you want to associate file types with a certain program so that a program is the default for it, follow the instruction below.

5. Step As you can see above the details tell me that the DivX Plus Player has 4 out of 14 defaults. If you want all media files that this program is capable of opening, then use the option Set this program as default.
