Hi,

I'm facing the same problem of extremely slow transfer rate in my new Smartphone. It's a Galaxy note 4 using Android 6.0.1, with a 64 GB SD Card. I used the "connect as wireless device option"

Previously, I used a galaxy note 2 (Android 4.4.2) with the same card. I also use Galaxy note Pro 12.2 (Android 5.0.2), and a Lenovo Yoga pro 13" tablet. On these 3 devices I never had any problem to transfer my books. Galaxy note pro and Lenovo had also a 64 GB micro SD Card.

I read the article where you explained to have tried different templates, and experienced the same slowness as the number of books increased. After resetting completely CC, the first 11 books where transfered in 3 seconds. Then 193 Books where sent in 8 minutes and 8 seconds : 10 times slowly.

I would like to know what changed ? Is it due to Android 6 ???

I don't understand anything in the way to modify the template for the file name. I would like to know where writing this template you gave as example.

My Calibre is configured to send books with the following template :
{tags}/{#category}/{series}/{title}. It did the following things :

All of my books have a tag (and only one) , it creates a folder following the name of the tag (only 19 existing)

In this folder, if something is written in a personalized column named #category, it creates a folder following the name of this column

Each books which is part of a series is in a folder named according to the name of the serie,

and each books has a name like this : [Serie name-Number in the series] Title

I have always proceed the same way and never had any problem, I use the same template to transfer books on eReader, and it works fine.

I wish to transfer 27 000 eBooks.

I've tried to transfer books, but when reaching 7500 eBooks, Time to transfer one book reach more than 23 seconds, and it was going worst and worst.

So please can you help me ?

PS/ I only transfer ePub format.
