Thank you Peter. You have at least put my mind at rest. I had to just leave the B2 doing what it was doing last night and go to sleep and not worry about it. I just had to think that the import would just replace what was there in some fashion or another. I got anxious lest it doubled up on everything!
Because of your words to me many weeks ago when I first embarked on this project then I am belt and braces. I put what is going to go to the B2 on a separate external hard disc, copy it to the B2, and then pretty much immediately, export to C from the B2. With the sunny weather I had not been doing any copying recently and so last night, having ripped some stuff and then copied to the B2 I was then setting about exporting to C. I guess I just forgot how to get to 'Export to C' and instead of down arrow, went Ok, and off it went.
It was finished when I looked at it this morning. It all looks ok and indeed even last night's items that were due to be 'exported' were still in there, so I have exported those now. I remember from past comments that anything that has been 'corrected' in the B2 after exporting will be brought back in its original state with the import, so there will be a handful of corrections needed to the naming of items, but finding them now will be like 'needle in the haystack'. The number of corrections had not warranted erasing the existing export but it does make me wonder if I should keep a note of the corrections I make rather than redo the export, or whether I should get a life and not be so anal about this hoarding.
As you say Peter, it would make more sense to have 'Export' first in the list, but experience is a powerful teacher and hopefully I will remember how to do this next time.
Thanks again.
Andy
