Folderview in Visual Studio

[EvertX]

I have written mods for other games before but this is the first time I am doing it in C# and working with Visual Studio Community. If I setup the folders and VS as described in the wiki and by tutorials I get a folderview (in VS) with the 'Source' folder at the root. Which I understand, but then how do I access the XML files in e.g. de 'Defs' folder? Or do modders use another program for creating/editing XML files? Is there a way to show the parent folder in VS's folder view?

Going to answer my own question and leave it here if anyone ever needs it:
Go to the solutions view and save the solutionsfile as a new file at the new root folder. Then close VS, delete the old file and open the new solution. Now folderview shows the new root.
