I'm back again, but things are going much easier these days for the most part thanks to all of the help here! Thanks again!

My issue this time is when I press the save button from a Winform to batch add. I'm using batch add because I read it's better to use it even if just one file. It makes it more flexible. I marked where the code breaks below. It does successfully create a folder, but fails to create the file. Any thoughts on what I'm doing wrong here? It breaks at the method buttonSave_Click() on line 91. Thanks again!

this is my error message:
