custom template suddenly stoppped working
I have the following template enabled on the Kobo:
Code:
Books/{:'current_library_name()'}/{#genre}/{title}/{authors}- {title}
This normally saves books under /kobo/Books/Calibre\ Library/<genre tag>/... and so on.

Suddenly, without any change to Calibre. books are being saved to the device under:

/kobo/Bs/CaliraryBm/<title>

I am using KOreader so file management is important to my workflow.

Maybe the path is too long (or at least exceeds a calibre maximum path length) and is being truncated

Have you checked that this is the setting in the driver when the device is connected? Changing between the KoboTouch and KoboTouchExtended driver does not copy the settings.

That does look like a truncated file name due to excessive path length. Are all books going there, or just some with multiple authors. The path length is limited to (from memory) 186 characters on the device.

If you only use KOReader, then I suggest not using the Kobo specific drivers. Use either the Folder Device Interface or the User Defined USB driver to connect to the device. With these, you will see what is on the device without needing nickel to be started and import the books.

It's not an issue with path length. I set my template to:

Books/{title}.

Some are stored under "Books" others under "Boks."

This happened when I used {formats}. Some were saved under PDF/ and others under PF/.

It still looks like a path length error. Add the length of the book file name to the directories. calibre basically uses the shortest length supported by any of the OS it runs on for all supported OS. That was the main driver for me modifying my save to device and save to disk templates to truncate the author list to the first entry.

Looking at your entry, adding the ebook title twice is likely not helping.

Code:
Elib/{author_sort:sublist(0,1,&)}/{title} - {authors:sublist(0,1,&)}

If that is what is being done, it is almost definitely a path length issue. It is easy enough to check. Just look in the directory and see what the longest file name is.

And the maximum length used for Kobo devices is 185 characters. It is much shorter than the 250 that calibre has because of things the device does with the name.
