I haven't seen any posts where someone has hooked their Kindle to a PC - would be interesting to see if collections show up as "folders" - might be worth a try.

It appears to be in [Kindle Drive]:\system\collections.json as a JSON object. It's hard to read the long, one-line string, so I parsed it into a PHP array and output that via print_r(), with this result shown below. The names in the format "#B002WAUVNC^EBOK" look to be easily derived from the files of those books downloaded from Amazon (ASIN number plus the "EBOK" label from the file name), but I've not yet guessed how the longer hex strings (starting with "*") are derived from non-Amazon books. I'm guessing some encoding of the file name, but...???
