Sen2Cor output


I run Sen2cor for S2L1C, and i selected 10 m resolution. The process is well completed but when I opened the GRANULE folder I find 3 folders R10 , R20 ,R60.

Is that mean I need to resample the output to 10m again in case I need the final resolution 10 m ?
The second question is if I selected the resolution 10 m, should the downsample 20 to 60 to be FALSE?

Thank you so much
