user9573: I installed the bitcoin program and now it's synchronising, and although I installed it on my very large D: disk it's moving all of the stuff on my little C: disk.
It's now around 6 GB in size with 45 weeks to go and I'm out of room. Is there a way I can safely move it to my D: or make it synchronise onto my D: instead?

user1873: You can specify where to store the blockchain by starting QT with the following command argument:
-datadir D:\BITCOIN


user9175: You can either start the bitcoin client with the command line option -datadir=<path to another directory> (you would have to do this every time you start the client) or you can link the blocks directory to another location. How to do this depends on your operating system:

For Windows I found this forum post (didn't test it but sounds reasonable)
On Linux you could do something like this: ln -s ~/.bitcoin/blocks /another/directory (make sure you use an absolute path for the source directory).
