Hello there. I've recently begun using Calibre as a book management tool, and today I have attempted to use the send to device feature to transfer files from the Calibre library on my Windows machine to my Android device via USB.
The issue I am facing is that when I plug in my Android device and choose to manage it on Calibre, it
immediately starts scanning the filesystem of my Android device for files without giving me a chance to configure what folder(s) I want it to look in.
The Android device I am attempting to transfer files onto is a device I use for more than just reading eBooks. As such, there are a fairly large number of files on it which would mean that full scan of the device that Calibre does on connection would take a fairly long time.
From the googling I have done, there is
one thread from roughly 10 years ago where the response to OP's question (which I will paraphrase) of "Is there a setting to turn off Calibre's auto scan of a device before the folders I want Calibre to scan can be configured" seems to have been to "disable the MTP plugin" (again, paraphrased).
I do not know whether this was an acceptable answer to the OP of the thread, but in my opinion this is a non-answer. I am not trying to avoid managing my device, I am trying to tell Calibre that "Hey, I know that this device is new to you, so I'm just letting you know that this is the folder on this device that you need to look in. Ignore all the other folders". I am trying to avoid wasting what could be more than half an hour of my time waiting for Calibre to sift through ~137 GB of files on my Android device looking for any files previously added by Calibre when I know they're not anywhere on my device.
I would greatly appreciate any information on whether it is possible to stop Calibre from scanning a device on connection and allow me to configure the folder's it should be looking in. And if this is not at all possible please do let me know as well.
