Metadata Change->Library Folder Structure?

[CC-GoE]

HI!
Noob here...
I did my first change in metadata of some books.
Specifically, I changed an author name, and also some book titles.
And saved my changes.
I went to the Library folder, which is handled by Calibre.
But, I see that both the author name, and the titles, have not been changed.
They are the same as before...
Can I do something, so that the folder corresponds to the actual new metadata?

It should automatically do that.

Are you running a cloud sync program? If so, you may have ended up with duplicated folders -- calibre moved them, but Dropbox/SkyDrive/Box/Copy.com/whatever restoredthe old versions.

Or storing the library on a NAS? that would prevent calibre from making the necessary changes -- NAS storage is heavily recommended against.

To test, can you try running Library Maintenance from the dropdown under the switch Library icon in the toolbar. Use Check Library. It will go in two stages, the first checks for database errors, the second stage will ask if you want to check that the database matches the actual files/folders. That includes a check for extra files/folders not associated with the database at all.

Thanks for the quick reply.

No. Not using any could sync program.

Nope. Don't even know what a NAS is.

Did that. First stage says:

Found no errors...

Then asks:

Do you want calibre to check...

I press yes.
And...

The files in your library match the information in the database.

Still, some book titles are the same as I inserted them in the first place.
Did some changes to them, but the actual folders have not been changed, but just left intact as in the first place...

@CC-GoE - what Operating System and File System are you using - and can you give an example of what you changed?

Yeah sure.
OS: Windows 7 SP1 Home Premium 32bit
File System: NTFS (2 Drives: C And D)
(Calibre installed in C Program Files)
(Calibre Library located in D)

Examples:
1. Had some books of Plato (http://en.wikipedia.org/wiki/Plato)
(Actually hehe I had it wrong before in English. Had used Platon and not Plato. Nevermind that.)
Change: Changed the author name, from Platon to Πλάτων (Greek)
The folder remains: Platon

2. Had some books of Paulo Coelho.
Those are books in Greek language.
I went and changed the titles of those books from Greeklish to Greek.

IE: Enteka Lepta -> Έντεκα Λεπτά

The folders under Coelho Paulo, remain the same in Greeklish.

3. Actually, in my Library folder, some titles are truncated and they are not even in correspondence to my actual titles in previous metadata changes.

IE1:
Title as I have in metadata:

Sams Teach Yourself SQL in 10 Minutes

Actual folder in Library:

Sams Teach Yourself SQL in 10 Minute (54)

IE2:
Title as I have in metadata:

Apache Maven 2 Effective Implementation

Actual folder in Library:

Apache Maven 2 Effective Implementat (39)

And others too...


So, it seems like my folders in Library, are not been updated to changes in metadata. Is this normal?

If you update author or title, then that information is used to give path and filename of your books. However calibre takes some liberties with the metadata. Characters are replaced and the items may be truncated to ensure that the path and filename is valid. And since calibre is cross platform, calibre is rather strict when replacing characters. Also a number is added inside parentheses.

The folder and filenames are automatically updated when you change author and title in the GUI. No need to save anything.

If you can't see the effects of the update, then you are looking at the wrong place, are mistaken about the current metadata or your calibre library is corrupt. Or perhaps all of this at the same time.

You typically shouldn't access the books from inside the calibre library. Instead use the GUI or save the books to an external folder using the save to disk template. If you access the books directly in the calibre library, then you may make the library corrupt.

As has already been suggested, run the library maintenance tools to ensure the library is OK.

WoW!
Hey ppl!
Actually, I found out the cause of my issues.
Everything is at is should be.
Except from this amazing little detail:

The Greek characters, are been translated/transformed to English ones!
Examples:

Πλάτων -> Platon
Τόμος Γ' -> Tomos G'
Ο Διάβολος Και Η Δεσποινίδα Πριμ -> O Diabolos Kai E Despoinida Prim
...

Together of course with the things you said, like truncating some filenames, and adding a number in parentheses afterwards.

So, it seems now, that my questions shifts to this more specific one:
Can Calibre support Greek and other Unicode characters in its folder structure hierarchy? Or is it, that Calibre will handle all Greek and other Unicode letters internally, and do those translations in its internal folder library structure?

NOTE: My metadata as shown in the GUI is 100% correct.
All Greek letters are shown correctly after I changed them...

CHEERS!

Guess this have to do with compatibility of file systems. Some do not support Unicode and / or special characters. The library design is set up in a way to support them all, what means with a limited common set of characters (ASCII code w/o special characters).
Using save book to disc, you have more control on this.

It really does not matter what name Calibre stores files as internally.
Its other job is to deliver the book to the device without you needing to know where it was stored in the library.
Project Gutenberg has been filing books as PG#### all along. Unfortunately, they also deliver them with that as the filename

When you edit a format file the name of the file (in some cases the full path name) is displayed by the editor you use, usually in the window title - including the calibre book editor, sigil, word processors, text editors etc.

If nothing else it can be disconcerting to find one is editing a file whose name is absolute gobbledegook - as happens with books whose titles and authors are written in Arabic, Farsi, Korean etc. Such as the EPUB for الأسود يليق بك by أحلام مستغانمي appearing in the calibre book editor title as al'swd ylyq bk - 'Hlam mstGanmy.epub

Imagine you had the Swedish book 'Snabb brun räv' in your library, and when you opened the PDF in Acrobat reader you saw الثعلب البنى السريع, rather than 'Snabb brun rav'

I am not suggesting anything should be done about it, but I am suggesting that one should try to appreciate the perspective of people whose language doesn't use the Latin alphabet.
