Good evening, when Calibre has to manage a large number of books (several thousand, or even more), we end up with a root directory of the library containing a very large number of subdirectories. This results in a slowdown on the operating system.

What do you think of a slightly different organization where we would have one entry per ID, for example, 1000 IDs per directory (1-999, then 1000 to 1999, etc.)? This structure greatly facilitates additions without having to check the entire library and significantly speeds up OS access.

Given that I'm using a read-only copy of the database via my own scripts, is it possible to update the metadata with this structure? For future updates, I would simply need to add the current directory with the largest IDs.

Votre avis ?
