Bitcoin-Qt setup: Change block-chain file location, settings? documentation? I am installing Bitcoin-Qt and have been reading about Bitcoin basics, but I found very little information on the client. I have a few questions about the Bitcoin-Qt program (v0.8.1-beta under Windows 7), 


Where is the complete Bitcoin-Qt documentation? I can not find it.
How do I change the file locations for the block-chain storage?

Block chain is ~6&nbsp;GB
The default appears to be MyDocuments\AppData\Roaming\
My C: system drive is small, and I have a second drive for such data.

Is the "Wallet" a separate file/entity from the block-chain?

How do I define the wallet's location?
Can I backup the wallet by simple copy/paste/tar.gz without carrying the entire block-chain?

Does the Bitcoin-Qt client currently have built-in mining/transaction-processing? I do not see the dialog-box to configure. I have a graphics card and ample wasted CPU-cycles.


Thanks for clarification. Links to proper documentation are welcome!

Use the -datadir option.
Right-click on your bitcoin-qt shortcut, press properties, and add -datadir=D:\Bitcoin
Go make that directory, then run bitcoin. If a bunch of files show up in there, you've done it correctly.
Yep.  


-datadir
File > Backup Wallet

Yes, but not GPU mining. GUI miner is a nice option though.
