Any way to make scanning for new books quicker?

I was doing some testing on my Forma. Available storage is down to ~1.4GB with ~2500 books transferred by calibre. I added 1 book and it took just shy of 6 seconds from when I clicked on the Smart Eject icon in calibre to when the book was imported and showing in My Books. Basically, importing started at 6%, jumped to 94% and then done. I reconnected to send the series info and took ~3 seconds before I was at the Kobo GUI after Smart Eject.

I then tried sending 88 books. It took around 2 minutes and 50 seconds to send the 88 books plus about 8 seconds to send the metadata. It took about 52 seconds from eject to import finishing (~1% per book, 0.6 seconds per book).

Sorry but I have trouble considering those timings as "takes AGES".

I then used KOReader and Plato to look for books using my default directory structure (Ebooks/author_sort/filename.epub). Personally, I prefer using either Nickel's search on the Kobo database or KOReader's search on metadata.calibre to trying to maintain a directory structure that is pretty much useless when you have a decent number of books on your ereader.

I'm assuming that your KOReader/Plato friendly directory structure is done by a template when sending the ebooks to your Forma. Otherwise, moving files after they are on your Forma would require all the moved files to be rescanned on the next disconnect or triggering a full rescan from NickelMenu.

Perhaps you should consider dropping use of the KoboTouch/KoboTouchExtended driver and going to KOReader/Plato directory based structure as suggested by @davidfor. Possibly look into the KOReader Sync plugin.

Are you saying the import takes a long time? Or it takes a long time until the import starts? My experience with adding a single book to my Clara HD is roughly what @DNSB mentioned. The import take is short enough that I can miss seeing it. This is on a device with 9455 books. How long it takes does not seem to be dependent on how many books are on the device.

But, what @DNSB did not mention is how long it can take until the import screen is displayed. There is a background process that runs shortly after disconnecting looking for changes. It also removes any missing or changed books from the devices database. This can take a couple of minutes on my Clara HD. Sometimes I get surprised as I start using the device without thinking and have the import screen popup. On devices with less books, such as Libra H2O with 1175 books, the scan is quick and not very noticeable.

As to sending the books when using KOReader, that will bypass nickel scanning for books. And if never use nickel, that is fine. But, in that case, you also need to use one of the other connection methods as the KoboTouch and KoboTouchExtended drivers read the database. They do not scan the device for books. Books are only considered to be on the device if they have been imported by nickel. That is not going to change. If you do not use nickel, then you need to use a driver that is compatible with the way the reading app you are using handles books. That would partly solve the issues you are having in the other thread, but, there would probably still be some issues with the way you have the author names. What they are I could not say as I do not use the other drivers and have settled on the simplest way to handle authors.
