A software like KM Player has been used for a while. I installed another software which was capable of playing media files. Most of the file-type associations has been reset to the new software and cannot be changed using the preferences/options of either of them.
I don’t want to change the association manually one by one. I thought using Windows built-in ‘Set Your Default Programmes’ tool can be useful in this case. Unfortunately, I cannot add software to the existing list.
Would you please help me with this issue?
