• It has not been updated for a long time, while still works for classic Kindles(released before 2024).

• Just in case you are still using it. Here is the official manual.
  Please be noted: Since Amazon did some USB/MTP changes, modern Kindle series (released after 2024) cannot be directly accessed by this Kindle Mate 1.3x(Kindle Mate 3 does this job). But you can get you clippings file/vocab.db file and import yourself.
