The folk guitar string you purchased with a tension of .10 is usually an extra light gauge guitar string, also known as a 10 gauge guitar string.
Guitar string gauge is measured in inches, and the measurement corresponds to the thickness of the string. The thicker the string, the greater the tension, and the louder and richer the sound. Extra-light gauge guitar strings, like the one you bought, have a lower tension and are easier to play, especially for beginners. However, they may lack the power and depth of sound of heavier gauge strings.
