Yes, that was what I thought too...

I tried copy the files to the ereader, since the ADE app on the phone doesn't have any option to transfer to external device. Like one normally do on the laptop.

I tried putting it directly in the root folder, since it's there the ADE app in Windows transfer it to. On the phone the ADE app puts the book in the ADE folder, so I also tried to put it in the ADE folder on the ereader. But without success.

Isn't it strange that Adobe doesn't offer the option to transfer from phone (or tablet) to external device, since more people tend to leave computer and use a tablet or phone these days? Especially when travelling.
