Ok, Sounds like horse has already bolted then.
1 I just kept the three folders mentioned above
2 My computer's been rebuilt so I guess anything in Roaming will be gone as I didn't know anything else was there
3 Suppose I'll have to remember to use back up next time
Disappointing, but not the end of the world. Would love to know what the point of the folders accounts, tasks and options is, if they're not the useful ones though!
Best wishes
