What I'm trying to accomplish by changing $HomeDirectory is very simple: when the Save As dialog comes up, the default location will be where _I_ want it to be (in e:\temp) instead of the Mathematica default of what I've set in Windows as the equivalent of My Documents. Directory temp is where I'm working now; Documents is stuff I'm saving "forever". I had hoped there was in environment variable for this, just as there are for $UserBaseDirectory and $UserBaseDirectory. I prefer to set such things in the OS rather than edit any init.m. It's easier and less likely to get lost when updating from on Mathematica version to another. But I guess I have no choice here. John Fultz wrote: > No, there isn't.
