KOReader Books or Collections View?

[iandol]

First off, thank you to the KOReader developers for a wonderful piece of software. I love the flexibility of tweaking the presentation of the text and all the other interface features.

I use Calibre to sync my EPUBs, and they are placed in author folders by default. In the Kobo or Plato top-level interface, the folders are not shown, only the EPUBs (a books view). In KOReader (not the history view but the file view), there is no equivalent view. Is there a way to see just the EPUB files, and ignore the folders?

EDIT: how can I add collections, I didn't find anything in the user guide or wiki?
EDIT2: I found how to add a collection, only when adding a book, not in the collections view...


Thanks in advance for any help!

There is no way to ignore the folders, but someone provided a related user patch that automatically adds all books to the Favorites, so they can be browsed in a flat view there:

While you're in a collection, you can tap the hamburger menu (top left) and select 'Add a book to collection'.

Just tell Calibre to not export to author subfolders and you will have a flat file structure.

Thank you to both for your help!

I already have >380 books in folders, and I wonder what would happen if I change this setting, it will apply to books going forwards, but what about the previous books. If I manually move (with a script) all EPUBs out of folders to root, that would probably break the links Calibre has for which books are already synced?

There are several workarounds from the thread @jonnyl mentioned apart from the patch, amazing how flexible KOReader is!!!

See and download https://github.com/peterstamps/All_e...ew_on_KOreader

This KOreader plugin organizes ALL your eBooks of type epub, pdf, awz3, mobi, docx into a single collection!
Many people asked for such solution on Reddit and other.

It works independent on how you have organized the structure (all books in one folder or like the structure that Calibre by default creates on your reader.

It works as a normal KOreader Collection and is standard called 'All Books'.
You can click on the 'hamburger - or three horizontal stripes at left upper corner' menu in the collection view to sort the collection list.

More than 10.000 ebooks in a few hundred folders of Authors is created very fast is a few seconds. After a restart the Collection is visible.

Under menu Tools (wrench/screwdriver icon) go to next page (page 2) and click on More Tools > Click on All eBooks Collection.

This will start the function.
That function can be coupled to a gesture that you like. I used swipe-up movement on right edge of my reader screen and that starts the creation of the collection. Always restart KOreader after a new creation process to make the collection and its changes visible.
I use swipe-down at right edge to jump to Collections list.

You can repeat this function without any problem.

Have FUN.

PS: I used inspiration from a similar solution that was created as a patch but that was always using Favorites and it had severe issues with large collections..only a few hundred books otherwise it crashed. Only epub and pdf were processed.
If you have other types like .txt that you want to make visible look into the source code and and that looks like this (find it around lines 160-165):

local pfile = popen('find "'..directory..'" -maxdepth 10 -type f -name "*.epub" -o -name "*.pdf" -o -name "*.azw3" -o -name "*.mobi" -o -name "*.DOCX" | sort ')

So if you want .txt then it will look like this

local pfile = popen('find "'..directory..'" -maxdepth 10 -type f -name "*.epub" -o -name "*.pdf" -o -name "*.azw3" -o -name "*.mobi" -o -name "*.DOCX" -o -name "*.txt" | sort ')

Note: I have tested it on Ubuntu, Radpberry Pi 4 Bookworm and Android. i expect it will also work on Kobo as I use standard functions of KOreader.
