And as soon as I read this I did remember a problem with long names. While the path name limit is 256 or 260 (can't remember where the extra 4 goes), the practical limit for a book is much shorter. This is because of the generated images. These are created with the full path of the book plus an identifier and an extension. And they go in a subdirectory. Because of this, the KoboTouch driver uses 185 characters as the maximum path length. There is also the files in "Digital Editions", but I thing this length covers them.

It's been ages since I tried this, but some strange things do happen when that books path length is to long. And it is because the path for the cover images is to long. I don't remember exactly what happened and would need to experiment.
