change branch abort, case-folding collision

[Uwe Brauer]

Hi 

I wanted to change to a different branch, but obtain

abort: case-folding collision between
Mini-Examen-Quim/13-14/Result-Final/Calificaciones_EstadisticaCalcNumerico13-14.csv
and
Mini-Examen-Quim/13-14/Result-Final/CALIFICACIONES_EstadisticaCalcNumerico13-14.csv 


Any idea how to solve this?



hg mv Calificaciones_EstadisticaCalcNumerico13-14.csv  CALIFICACIONES_EstadisticaCalcNumerico13-14.csv 

But it did not help

Regards
