The library list the Kobo shows is not file explorer, it is a list of books and book-like things it knows how to handle. If there are files on the device that the Kobo firmware does not know how to handle, it simply ignores them.

I don't download to Kobo. Usually wifi is off. I download to the computer, then transfer to the ext.drive - on my computer, that's usually f. I don't use the Kobo desktop, either. It's disabled on the computer. I use usb cables.
I do have to use Amazon Desktop if I buy from them, but it gets disabled after use.
If I have a mess of books on a usb device or another card, I use Calibre. There is a heading for device and one for card. I use card. Card to me is external card. Device is internal memory.

Yes the device is the internal memory and the card is the external SD card. Or at least it is for the Kobo devices.
How? Within calibre or outside calibre?

I switch the card between and Android tablet and the Kobo.
I'll see books in triplicate on the Kobo, check the internal memory, and the external card, and I don't see the listings. Kobo will add the book in the original file format if it's been converted, and by doing the highlighting all the epubs and pdfs, I found out that where the format tag is matters. If epub is first in the list, it gets included with the epubs. If epub is last on the list, it is overlooked. Example - converted Amazon. Amazon's AZW3 or whatever shows first in the formats, then a comma, then epub. epub is totally ignored in that position. Same with PDF.
Somehow Kobo is seeing both tags and putting both files on the card, even if I only say to send one. (the epub) If I hook up to the computer, I only see one file. On the Kobo, there are 2 or possibly 3 copies of the book. Kobo Library shows only one copy.
I'm still using the last 3.15 ---- whatever.

When do you see books in triplicate? Using the Kobo device in the library? If so, unless the the database on the device is corrupt, then there are three copies of the book on the device. While the firmware doesn't display the file location, it differentiates books based on location. If you have three copies in different places, they will be treated as three books. If you have PDF, epub and mobi versions on the device, they will be treated as different books.
In in calibre, the books on the device come from the database on the device. It it has three copies, then calibre will show three copies. The could be in the main memory or on the card.
The rest, I'm not sure what you mean. If I send a book to the device, the format selected is the first in the list in the driver configuration. By default, that is kepub and then epub. As I don't keep many kepubs in my calibre library, that means the epub is sent.

The Android 4.1 tablet doesn't do this.
It's looking like I might have to find an e-ink Android and get rid of Google. I don't need a Google account for books. I can purchase on computer and download.
You had articles about changing to linux on the e-reader. I'm familiar with Ubuntu and Mint, but even those give file formats on the computer. Would they do the same on an e-reader? I'd need a step by step. I've done phones but only used CyanogenMod as they had the best instructions, step by step.

The Kobo firmware is actually Linux running a proprietary application on top. You can to kill this application and run something else. Such as KOReader. Plus there are people running their own Linux builds or Android on different Kobo's. If you're interested, look in the Kobo forum here.
