How to make Bitcoin-Qt client portable? (Windows) It is a nice project and all, but I think in 2013 it shouldn't be a challenge to save all of an application's files into its own folder (maybe even by default), so you can use it without installing/uninstalling.

I just don't have that much space on drive C. I use drive D for stuff. Is there a solution?

Google just brought me to this discussion which lead to all the fancy alternatives to the original client. I just want to try original Bitcoin-Qt first.

Would no one be interested in a portable Bitcoin-Qt? It would be very useful in my opinion.
Put the bitcoin-qt.exe binary in the folder
Create a bitcoin.bat file
Open the file with notepad
Add the following line: bitcoin-qt.exe -datadir=.
From now on you can start by double-clicking the bat
