I had this problem in Beta 2. This is in my opinion, a serious flaw with
Vista. The way the file system works is very strange to me. Try switching
your Vista drive to an XP machine and doing your search. You will find your
files in a sub folder of your user name local files. But it seems to be
different from the normal local files folder.
You will never find the file searching your disk from Vista. It was possible
for me to find the parent folder after knowing what to look for, but was
denied access from within Vista using any level of credietials available to
me. I COULD access the folder and subfolders using XP. When I originally
downloaded the file it said it would be put into the My Documents folder.
I first noticed something was wrong when trying to attach files using
windows Live Mail Although the file I wanted to attach was right on my
desktop, windows live mail couldn't find it. So when I had downloading
problems I spent a little time poking about. Best as I can tell it's all
some kind of smoke and mirrors virtualization re-direction scheme
("sandboxing", I think it's called).
That gave me a very creeped out feeling, because with Vista, stuff can be on
your hard drive but you would never know it even if you suspect it is there
and activly look for it.. May be true on XP also for all I know, the more I
think I know, the less I know, it would seem.
