INFO: Confidentiality statement

Any information (including books.db file) submitted at www.aar-innovations.com is not used otherwise than to extract highlights from books.db and make these highlights available for download. This means that books.db is permanently deleted immediately after the extraction is complete, and a file with highlights is stored on www.aar-innovations.com during one (1) hour after the completion of extraction. After this all files are permanently deleted and will no longer be available (thus, you cannot share links to your files with extracted highlights).

HINT: How to connect an e-book reader (PocketBook or Sony PRS) to a computer

(a) Turn on your e-book reader and computer

(b) Plug-in the USB cable to the computer

(c) Plug-in the other end of the USB cable to the e-book reader

(d) The e-book reader may request you to answer a question about the connection:

PocketBook: may display the following message: 'Select the USB mode'. Select the 'PC link' answer.

Save ebook annotations

(e) The computer will recognise your e-book reader, and it will look like a hard disk or removable USB drive.


Export ebook notes

STEP 2. Choose a 'books.db' file:

HINT: What is books.db?

All highlights / marked text made in the e-book are stored in a file named 'books.db'. This file is located on the e-book reader.

HINT: Where to find books.db?

The 'books.db' file is located on the e-book reader. After you have connected the e-book to the computer, you can access 'books.db':

PocketBook: D:\system\config\books.db ('D:' is a PocketBook drive letter and may vary).



Some users may experience difficulties with finding the '\system\' folder because it is hidden (simply speaking it has a 'hidden' attribute selected). Please read PecketBook's official answer to the question 'I Cannot Find the System Folder' here: http://www.pocketbook-int.com/us/support/faq/198/3113

Sony PRS: D:\Sony_Reader\database\books.db ('D:' is a Sony PRS drive letter and may vary).

HINT: Sony PRS' highlights character limit

Sony PRS readers allow to highlight any number of characters in an e-book but store only first 200 characters in 'books.db' file. Therefore, if your highlighted phrase is longer than 200 characters (including spaces, commas, etc.), then everything exceeding this limit would not be saved to 'books.db' and would not be extracted.
