Hi board members

Can I save my lightroom 2.4 settings so the next time I re-format I can re-establish lightroom with all the "Smart Collections" I have built?

I have noticed a lightroom folder in "My Pictures" and have begun backing this folder up to D: - I reckon this may the blighter.

Now, assuming I'm right about this being the folder where the "Smart Collection" data is stored - can I just drag it back to this location after a re-format or does it need to be imported?

How do you do that? File/Auto Import perhaps.

Help is always appreciated.
