If you want my opinion...? Forget all about your folders.
Right now, you're (effectively) anonymous. Apart from the "25 years..." clue, nobody has any idea who you are. You're just another public that has fallen off-lines. One of many thousands, as Scn has shrunk by more than half since this century began.
Until you draw attention to yourself, nobody's going to pay attention to your PC folder... no matter what you feel that you confessed over the years. So much of Scientology is founded upon make-believe and ego-massaging nonsense (past lives, for example) that nothing recorded there could really be held against you. Also, it will have been recorded with classic Sciento-incompetence, interpreted with classic Sciento-buzzword-of-the-month drivel, and filed with classic Sciento-all-hands-urgency... meaning that if it can be found at all, it's probably more trouble that it's worth. More than a few PC folders have turned up in dumpsters before now, you know... Document storage is expensive, and Scientology is obsessed with making money, not spending it. When your city's Ideal Org scam fails (as they all do, nowadays) your documents will be torched. Failing Scieno-scams often lead to arson,
as we know.
Now, if the Scientology victims do decide that you need to be attacked, and they try to release information about you... think about where Scientology's reputation is nowadays. To many people (including a lot of journalists) Scientology equates to "cult of liars, created by a liar"... so any information they try to leak about you will most likely be interpreted as the desperate act of a spiteful, failing mafia-like organisation.
Unless you really want to stir up some trouble, I doubt anybody will ever look inside your PC folder again. If you get yourself labelled as an SP, and if OSA are stronger in Denmark than I think... maybe. But in general OSA seems to be a pale and feeble imitation of what it once was: look at the farce of the 'Squirrel Busters'. If that's all they can manage against Marty the 'arch enemy of Scientology', they're not going to manage a whole lot against you.
You're out. You're back in society. Welcome! Society has changed a LOT in the last 25 years. There are very few taboos left. I doubt there's much in your folders that would even seem interesting, never mind scandalous.
Leave the remnant of Scientology sitting on its pile of dusty old documents... and have a great life!
