Create folder hierarchy

Hello all!

I need a function that creates folders,

create folder A on target "C:/test/123/"

if folder A exists on target "C:/test/123/" then create folder B on target "C:/test/123/"

if folder B don't exists on target "C:/test/123/" then create folder B on target "C:/test/123/"

if folder B exists then create folder C on target "C:/test/123/"

Could someone help me with this function

Thank you in advance
