There are many ways to do this. Basically you'll have to traverse the file system and add to treeview. What have you done and where are you stuck?

If you look at Directory.GetFiles, you will find it has an overload which returns all files in subdirectories as well as the specified folder.
string[] files = Directory.GetFiles(path, "*.*", SearchOption.AllDirectories);

It would then be pretty simple to sort them using Linq methods:
var sorted = files.OrderBy(s => new FileInfo(s).Extension);

Then all you have to do is display them in whatever way your feel like!
