We get similar inquires from time to time over at the exjw subreddit, people wanting their "file".
Lots of times it comes down to Where you live. Privacy laws and data retention laws vary.
I have heard of People in Australia getting their files, most notably Paul Grundy of www.jwfacts.com fame. Similar stories from EU countries.
In the US? Not much luck. Where I live in TX? Hell would freeze over first before you got to see your "file"!
The only (hypothetical) situation I can see, would be to have an Elder who is aware and sympathetic "loose" your file. The Secretary of your congregation would have it locked up in a cabinet at the hall.
You could always have a sneaky M.S. with the keys to the KH pick the lock to the file cabinet and grab it!
Anyways... Welcome C Lynne! If there is any kind of question you have, Please Ask!
