Convert list of all folders and subfolders of unit c:\ to an XML file in c#

I want to make a small program in C # that allows to load a list with the path of all folders and subfolders of any unit, eg "C: \", to an XML or any other file type. The goal is that after this, the file will serve to another program that I have to do a search and open particular folder.

It is possible to do this?

Thanks,
