[BetterRed]

@james14 - I think you have to set it to the folder where the books are - looks like that should be something like ...\Documents\Calibre\VC Andrews

But if you use the blue button at the right end of text box, you can navigate to the folder where the books are in the Choose Folder dialogue, then you can be sure that its right.

Added - But I'm wondering if you might not do better to use the Add books from a single directory - unless you only read book written by V.C. Andrews
