Well that change does let Koreader's File Manager see hidden files/folders and those with .Filename format. Nickel doesn't try to process the files on the test SD card that are in a .folder. So, it works! Now I will have to try and make a full sized uSD card with the folders behind/under a .folder.

We may finally have an AuraHD that can have a truly large collection of ebooks in defined category folders, that can contain files in a larger number of formats, all readable with Koreader. At the same time we can use calibre to load the internal uSD card with files easily processed by Nickel. The best of both worlds and with your hack their will be no conflicts.

Thanks;

OK, it is working fine with a larger file structure. All good to go. If only the File Manager had larger text and larger easier to select active points. It would be just right, for me.
