I'm investigating if there's a way to relocate the default location of the C:\BuildAgent\system directory. The agent is already installed, and I guess I could reinstall the entire agent on another disk, but simpler would be to add a line in buildAgent.properties. Is that possible? If not, consider adding it :)
I presume another way would be to add a file system mount point and redirect the mount point to another disk, but I don't feel as comfortable doing that in windows as I do in Linux, so a setting would still be the best solution for me.
