[Leica] lightroom questions

[Steve Barbour]

a few generally easy/straightforward lightroom questions....I guess....

1. where are lightroom images stored, can a particular image be found on the hard drive
2.if you wish to pull a particular lightroom image for use, can it be done
3.when you are done an image in lightroom develop, can you save it to where you wish for a specific use 
4.how do you sort, order, eliminate images in lightroom for use in a book



trying to come to grips,  help please....there may be a few more.


many thanks,


Steve
