Running BOINC 4.43 and only SETI with 1 WU on my disk, my "Program Files/BOINC" directory is 11 MB. I think WUs are around 400K each, so you can figure out about how much more space you'll need for cached WUs.

Are you sure your Windows account has full control of the BOINC directory on you disk? Have you checked the "Disk and Memory" settings in your preferences?

Help and BOINC documentation is available here.

1) How much space BOINC needs depends on the projects that you are attached to, the size of your cache and how many CPUs you have. Most projects have input and output files that are less than a meg. The exceptions are Einstein where the input file is 11 MB but it covers several WUs and CPDN where the output files exceed 700MB. Most of the projects need a scratch space of less than 10 MB per active WU. BOINC itself needs around 12MB or so.

2) You can place limits on it in the general settings of your account on the web. General settings are copied from project server to host to project server until all projects that you are attached to have been modified to be the same. There can be only one.

3) Not at this time.

BOINC WIKI

I'm trying to run BOINC but for some totally mystifying reason when it tries to write the results to the hard disc it fails. THe more promising work around I have found is to create a RAM disk - except that with the RAM disc it says there isn't enough disc space available.

SO, 3 questions -
1) How much disc space does BOINC need?
2) Is there some way of regulating it?
3) Is there some way of persuading BOINC to put data in a specific location (rather than the directory it installs to)
