I just updated my "school" venue. It appears the minimum disk space to leave is 0.1GB. I tried to set it to 0.05, but defaulted to 0.1 GB. The project (SIMAP) allows a 0.001GB setting.

I use this on my 486--(yes, I know!). OK, nobody but me cares, but this a big difference for the 345MB hard drive that BOINC uses.

I just wanted to cast a vote for all the computationally challenged people out there for a smaller minimum value.

And yes I do have real computers too. I just don't throw anything away :-)
