What is an AZW3R file?

An AZW3R file is a notation file used by Amazon Kindle, an eReader app. It contains data used to show a user's notes, highlights, and bookmarks in an associated .AZW3 eBook. AZW3R files typically have the same name as the AZW3 file with which they are associated.

More Information

In Amazon Kindle, readers can take notes, make highlights, and leave bookmarks in eBooks they are reading. If the eBook is an AZW3 file, Kindle will save the reader's notes, highlights, and bookmarks in an accompanying AZW3R file.

AZW3R files are saved in the same directory as the AZW3 file with which they are used. Typically, this is in Kindle's .sdr sub-directory. While AZW3R files are not meant to be opened by users, some users have created utilities that allow them to extract the notation AZW3R files contain.

How to open an AZW3R file

You can use jps-e azw3r tool (multiplatform) to extract the data an AZW3R file contains. For example, you can use azw3r to extract the notes an AZW3R file contains or a list of the locations at which a user highlighted a book.
