@Stephen  Sorry, Duncan's right, it is likely not a protected/hidden
file issue.  At the risk of nuking the fridge, you could also open an
elevated command prompt then navigate to the relevant directory and
delete the file:

> cd C:\Users\satimis
> del .RData
> exit

Probably too much trouble for deleting a single file, but handy if you
want to do a lot (e.g., all files with the *.RData extension or...).
The new PowerShell is starting to grow on me too (it seems wider), but
I am not as familiar with the commands.

@Duncan  You're right, as usual.  I mixed Windows and Linux.  Changing
the setting for extensions is basically as you described on my Windows
7 except I have to hit the left alt for Windows Explorer to even show
the file menu where I can click on Tools -> Folder Options (maybe just
my configuration).  Does .RData get registered by default but not
.Rhistory? (since Stephen reported seeing the .Rhistory file).
