Hi, John.
Yes, it worked.
Using Quicken's Backup command (Ctrl+B), I browsed for the Destination folder to J:\Users\RC\Documents\Quicken and clicked OK - and my current fileset was saved to that folder. Quicken reported success.
Then I used Find Quicken Files, and my new .qdf file in that J:\Users\RC\Documents\Quicken appeared. Windows Explorer shows the full
7-file Quicken fileset in that folder.
This is in Win7; I'm confident that the result would be the same in Vista, but I'm too lazy to try it just now.
As an additional test, I tried to Backup my current Quicken file to C:\Users\RC\Documents\Quicken, on the other partition (C:) where Vista is still installed, and Quicken refused, saying, "Unable to access the disk in drive C:." I did not pursue the matter by trying to give myself permission to access C:\Users\RC.
Now I'm going to go delete those files in J:\Users... before I forget that they are there. ;^}
