200,000? Yes, I'm exaggerating. I didn't have time to look at what's filling the HD.
12MB? No exaggerating. That's when I stopped.
As far as mail, all I got was an error saying something like "Not enough memory to complete this task", regardless of what settings I put in.
Went to my Mac, added account no problem, so at least I know her mail is working.
She took her laptop, and will be buying a new HD for backup.
No need to call. YET…
She'll be back in a couple days.
