Thanks for the response.
Before I answer your questions, I want to make sure that we're on the same
wavelength here. In your example, the actual folder name hasn't changed
(which is what I was complaining about originally). CO:USERS\USER was first
associated with USERA, and after my change, the *same* folder is now
associated with USERB. So everything is still kosher, but it's going to
cause some confusion for another person looking at it. I could find out for
myself, but as long as you're handy: can I rename the folder to
C:\USERS\USERB to regain consistency?
Why do I want to rename the account? It's kind of stupid, but whatever...
I had backed up all my stuff from one account to an offline backup system.
My PC got sick (I'll skip the details), so I erased the hard drive and
reinstalled from scratch. I decided to be smarter about the user names I
assigned, but I was concerned about restoring from the backup system to a
user name that it didn't know about, so I used an old name just for
restoring, and intended to rename it later. Of course, I found out later
that it wasn't necessary to do that, because the backup system has a
"Restore to ..." option. (!)
How much data? 32GB of photos.
If I can't rename the folder, I will probably create a new account, move the
data, and remove the old account as you suggested.
