How does N@H select which hard disk to use for work space?

(moderation:
I have this problem, that N@H seems to use my system disk C:-drive as work space. This has a very little capacity, so N@H often gets no work due to insuficient space.
Is there any way to make N@H use another disk drive, which holds plenty of space?

BOINC will always use directories below the path where the executables were installed as working directories. The default is c:\\Program Files\\BOINC or whatever is the "Programs" path on your Windows installation. Safest would be to re-install BOINC on another drive.
A detailed walk-thru of the procedure that prevents any loss of account data can be found here (please read the whole thread):

People often make this sound

People often make this sound far more complicated than it really is. The following steps are precisely what you need to do. If you don't fully understand a particular step, please ask for clarification:-
*Uninstall BOINC (eg Add/Remove Programs for Windows)
*Move the residual BOINC folder (contains all your data) to the new location
*Reinstall BOINC (same or newer version if you wish) making sure to specify the new location so that the default location doesn't get used.
That's it! At the end of the install process, BOINC will launch and will find all your data files in the new location and will simply pick up from where it left off without missing a beat. I have done this many times without incident and I don't even bother to make a backup since the process just simply works for me. If you want to be ultra cautious you could make a backup copy of the BOINC folder before attempting to move it to the new location.
I even use the above list of steps if I'm intending to decommission a machine and replace it with a better one (as long as it is the same OS). I don't bother to run down the cache of work on the old machine before shutting it down. I simply move the residual BOINC folder to the new machine using a network share (or a pen (USB) drive if you don't have a network share) and reinstall BOINC. BOINC will automatically fix things like hostname, machine description, IP address, benchmarks, etc, without any user intervention. If you are also taking the opportunity to upgrade the version of BOINC, new benchmarks will be done immediately. If you were using the same version of BOINC it would be a good idea to force benchmarks to be done immediately after the install. If the new machine is significantly faster, the higher benchmarks will skew the duration correction factor (DCF) and a manual ajustment of that would help to shorten the time to achieve stability of crunch time estimates.

Thank you for your instructions, which I have followed successfully, well Gary's most as this was the easyest.

RE: People often make this

As a side note to this post. These instructions are also good for two other cases:
1) You want to move constantly changing files off your C drive so your back-up software doesn't have to deal with it. (My system is broken up so data that changes all the time ((mail, caches, Boinc, etc)) are all on my D drive, where as my C drive stays pretty much the same.
2) Vista has problems with permissions if Boinc is in the Program Files directory.

There's one extra option on BOINC 5.10 and above.
By using the cc_config.xml file and the option entry
