Question: I'm sure this has been asked many times before, but I've recently gotten into the whole cryptocurrency thing starting with Dogecoin, and I now want to use Bitcoin as well. I am on Windows 7. I found out the hard way that downloading the blockchain through bitcoin-qt takes forever, so I went to <https://bitcoin.org/bin/blockchain/> and downloaded the torrent rather than waiting ages. I now have bootstrap.dat ready, but I don't know where to put it. I have two storage drives - a 120GB SSD and a 1TB hard drive. Because of the SSDs small size and the amount of small writes that bitcoin will do I opted to store the client and blockchain on my HDD. According to <https://en.bitcoin.it/wiki/Data_directory> I need to place the file at %appdata%\Bitcoin. Since appdata is located on the C drive, there is no bitcoin directory there. The rest of that article is for other operating systems.

Where should I place the bootstrap.dat file?

Answer: 
You can simply create a folder in %appdata% called 'Bitcoin' and place the bootstrap.dat file right in there, or start Bitcoin, close it, and the folder will be there :)

Once you have copied bootstrap.dat you can open Bitcoin (again). After completing, Bitcoin will rename bootstrap.dat to bootstrap.dat.old at which point it can be deleted.
Yes, confirmed - copy to `C:\%userprofile%\Appdata\Bitcoin\`

Relaunch the Bitcoin client. In bottom left, it will say "importing blocks from disk..."
