How does the Kindle tracks reading progress for each book?

I am trying to understand how the Kindle tracks your reading progress through a book, like the percentage read. Does anyone have any idea? I am using the KOreader file explorer feature to browse directories and look for files, but didn't have any luck so far.

My goal with this is fixing those books you download, never ever ever opens them, and still they are stupidly at 0%. That annoys me to no end, I want them to reflect the fact that, until I decide to open the book, they should be displayed as "NEW".

In the end, maybe this could be something I would make available for people interested, I know there are some who wish you could just reset the progress to new from digging about the issue a few years back.

I think that some column or columns in the sqlite database cc.db somewhere under /var controls whether "NEW" is displayed.

thanks! yeah, seems like the p_percentFinished column in the Entries table holds the percentage read for each document, a NULL value seems to point to a NEW book and anything other than that is a percentage going all the way to 100%.

will be a cool project to make this into something useful for other people.

There is also the j_displayTags column, which seems related to what is displayed, but I have to test it more to understand how it works (seems to hold enum values).
