How to merge two folders with Dropbox.Net SDK?

Hi XiangZhou,

As seems, there is no option to 'merge' files/folders using move by now. What you can do depends on what exactly you want achieve. If you just want to replace the existing folder, it becomes easy - delete the existing folder and move there the desired one (on the follow up try, after the remove). In such a way entire content of existing folder will gone (doesn't matter are there parts that don't overlap). If you want to keep non overlapping parts, you have to implement recursive algorithm that walk through the folder tree of the source folder and perform try move (eventually followed by delete and move) for files only. At the end, you'll need remove the source folder (there will be eventually empty subfolders only). If you want to merge files content further, then some content specific algorithms will also need as a part of the recursion.

Hope this gives direction.
