[Kobo] Calibre doesn't create subfolders anymore ?

[Cyril Gabard]

It's not a big deal but i noticed, exploring my Clara in USB, that Calibre doesn't create subfolders anymore on my ereader when i transfer books. And it renames the book file with numbers (for example 3761.kepub.epub). A few months ago, it used to create subfolders and the title of the file was more like : blablabla.kepub.epub (not numbers). I configured the device in Calibre so it creates subfolders...

Did you upgrade to Calibre 8+? If so, the update disabled the KoboTouch Extended driver since it's functionality is now part of the stock KoboTouch driver. However, the configuration from the KoboTouch extended driver is not transferred over and you will need to re-do it.

I use the following template in the KoboTouch configuration as the Save template:

eBooks/{author_sort:sublist(0,1,&)}/{title} - {authors:sublist(0,1,&)}

Basically, eBooks is in the root of the exposed storage, subdirectories based on the first entry in the author sort list are created and the ebooks are saved with a filename title - author where author is the first entry in the authors list.

I.e. The ebook Goth Drow Unleashed Omnibus by Martha Carr & Michael Anderle would show up in the physical storage as:

eBooks/Carr, Martha/Goth Drow Unleashed Omnibus - Martha Carr.kepub.epub

The reason for truncating the author sort & author entries is simply that the Kobo metadata gets the full information and it shortens the filenames & paths. Especially useful when you get an anthology such as The Big Book of Science Fiction with it's 104 authors and 2 editors.

You'd be best (IMHO) to not use variable directories such as author directories. Kobo doesn't use them or care about them. And if you delete eBooks from the Kobo use the Kobo software, you will eventually end up with a lot of empty directories.

Interesting. I used to have the Kobo Touch Extended plugin for my Kobo Sage. Looking at the file structure on my Sage, it looks the same now (with Calibre handling putting kepubs onto the device) as it did with Kobo Touch Extended. I'm almost positive I didn't change the Save Template for the Sage. It's currently:

{author_sort}/{title} - {authors}

But, maybe I'm looking in the wrong place. I get to that Save Template by right-clicking on my Kobo Utilities icon, selecting Configure Driver, and it's at the bottom of the File Formats tab.

If we're sharing our save templates, I have

Books/{author_sort[0]}/{authors}/{title} - {authors}

Which give me /Books/M/Christopher Moore/Noir - Christopher Moore.kepub.epub

This sorts the books into 26ish folders based on first initial of last name. Also, since all the M authors are in the same folder now, it's easier to find the author I want with the first name. That won't work for most of you, but it works for my brain.

Keep in mind that if you change your template, you can't easily send a replacement copy to your Kobo and have it overwrite your original. Once I settled on a new template, I made sure that all the progress bookmarks were saved to Calibre, I deleted all the books on the Kobo, and reloaded everything with the new template structure.

It's important to remember that if you had used (and configured) the native Kobo Touch support prior to installing Kobo Touch Extended, that the upgrade to calibre 8.x would have copied whatever had been configured for the Kobo Touch driver.

So if you had originally configured Kobo Touch to create sub-folders, then installed, configured and used KTE, calibre 8 would have used your original settings from Kobo Touch.

That is, I believe, the original default template. I modified it by adding the eBooks directory and forcing the author_sort and authors to use only the first entry. The issue I had with the default template is that the author_sort subdirectories are created in the root of the exposed storage and with some of my anthologies the filename became overly long. Adding a master directory and truncating the author-sort/authors saved me from those issues. Remember the root directory of a FAT32 volume has a maximum of 65535 directory entries and using long file names, you need a directory entry with the short filename plus an entry for every 13 bytes in the long filename so directory entries in the root can get chewed up rapidly.

Thank you all guys. Not only it came back using {author_sort}/{title} - {authors} but also i think i understood your explanations !
