An application doesn't have a "resource folder". Your project has such a folder because that's where the source items are stored but the whole point of resources is that they are data compiled into the EXE itself. As such, they are read-only. If you want a common location that all users can safely write to then use the public documents folder.

As for your code, if you add a file to your resources then it's the contents of that file that gets compiled into the EXE and returned via My.Resources. There is no file at run time so there is no file path at run time, so your attempts to create a StreamReader and StreamWriter are bound to fail. I assume that you have added a text file as a resource. In that case, My.Resources.FavoriteList is going to return the contents of that file as a String. You can use that data but you cannot modify it and save the changes back to the resource because that resource is part of your EXE.
