books saved in wrong directory on nook 4e

[Serge N]

When sending a book from Calibre library to the device, Calibre creates a folder called "My Files" in the root directory and places the books in there. Nook does not search that folder and does not read any of the books placed there. However, if I move the books over to the folder called "NOOK" in the root directory, then it works. I can't find a way to set the default directory for a device in Calibre settings. Calibre works fine with a much older nook device I have, so I guess at some point nook software settings changed but Calibre either doesn't have a separate profile for newer nook devices or doesn't correctly recognize the device.
Using latest version of Calibre (6.5.0 64-bit) on Win 10.

You can right click on the device icon in calibre and choose "Configure
this device". Is this an MTP based device? If so, if you send me the USB
ids for the device I can add detection for it to calibre.

Run

calibre-debug -d

in a command prompt with the nook connected and send me the output

Here is the debug log. The device ID for nook is the one that shows up in that output - 2080/000e/4.09.

For reference, my older Nook device shows up as 2080/0003/2.16 instead

[Kovid Goyal (kovid)]

Fixed in branch master. The fix will be in the next release. calibre is usually released every alternate Friday.

Hey, I just got to testing this out.
It works but I'd love it if you could adjust it a bit further. In the Nook interface's library view, there's a filter to view "all types", "books", or "my files". Books sent through Calibre show up under "my files". This corresponds to files being placed into "NOOK/My Files" folder on the device. And putting files into the "NOOK/Books" folder makes them appear under the "books" view. Books downloaded through the Nook store show up under "books" as well (though they seem to be stored somewhere else). I would love if Calibre used the "NOOK/Books" path instead of the current one of "NOOK/My Files/Books" but it's purely cosmetic effect as I can now view Calibre-transferred books on the device.

[Kovid Goyal (kovid)]

sure, next release.
