Searching for folders

[Tjeu]

I have a lot of nested folder which needs to be sorted out.
It would be a lot easier if I would have some code which would go trough all my folders and makes a list of each folder which has a subfolder called Mapping.

For example search trough all folders in C:\Temp

C:\Temp\folder x\ other folder\Mapping would return C:\Temp\folder x\ other folder
C:\Temp\folder x\ other folder\folder y\ would return nothing as there is no folder called mapping

but if there is then inside:
C:\Temp\folder x\ other folder\folder y\folder z\Mapping it would return C:\Temp\folder x\ other folder\folder y\folder z\

Hope you understand and can help me. I have no idea where to start with this. Couldn't find any help so far on the internet.
