Pinky And Sincerre Should I Use My Pinky When I Finger Pick My Guitar?

Should I use my pinky when I finger pick my guitar? - pinky and sincerre

Normally I use my thumb, index, middle and ring fingers. The best tips for three strings, and the pointer, middle and ring fingers in the last three strings. I play a lot of people during the removal of the fingers. I play this way for two years. Is there a reason or the style of my little finger?
