Convert a folded distribution to normal distribution

Hello

Need a little help.

If variable y=|x| is described by Y(m,σ) which is a folded distribution

what is the m and σ of the X distribution which describes x?

I know that X is a normal distribution but the problem is

how are m and σ of these two distribution connected.

Thanx
