1. Roughly 5GB
2. Addresses are on wallet.dat and is separated from snapshot. (Backup wallet.dat!)
3. Yes as long as the transaction has been confirmed.
Thanks for these useful answers. I finished downloading the Snapshot. It's folder that contains the following files:
blk0001.dat
blk0002.dat
db.log
log.0000000038
txleveldb folder with a bunch of .sst files
I have no clue what to do with all this Sorry, I am that much of a novice at this. So how do I use these files to synchronise my wallet more quickly? I thought I would just download the Snapshot and press a magic install button.
