Thankyou to the three of you for trying!
I gave them all a go - didn't get anywhere. The "personal folders" attempt (APPOEU) did generate a list called "personal folders" but it was an out of date copy of the original "personal folders" from the top of the column on the left..
The ones I'm trying to get across are labelled "Archive by topic".
The <Application Data> folder mentioned by NTOG is in my computer somewhere, I know - I've seen it. Buggered if I can find my way to it though. Don't even know which computer it's in, but still looking.
