In the future you might find it convenient to post one topic with
the subject indicating the post content, rather than two unrelated
questions which, as here, may not belong in the same newsgroup.

Try settings the NTFS permissions on one of those EFS encrypted
files so that some other account has Full Control at NTFS level.
Then log into that account a try to access the encrypted file.
You will get an access denied message. If that account attempts
at lower-level to read the bits from disk it will just get AES
encrypted bits.

EFS is supposed to be transparent to the allowed account.

The color shading you noticed is an optional setting in how
Explorer displays items that are EFS encrypted.

The return of the checkbox on the folder to its inital gray
appearance, after you had used it to set the folder to encrypt
contained files, is normal. That checkbox, like the Read-Only
box, on folders is not an indicator of state but is a switch to
use to set encryption, or read-only, on/off on the contained
files. Being EFS encrypted (or being read-only) is (are) not
actually properties of the folder but of the contained files.

Thanx to Steve Riley, Greenie LeBrun and Roger Abell for the 3 distinct and
very
informative replies. That about covers it. I will send this same reply to all.

Sori for late reply. No line yet here and I got R Arthritis so bad I can't
go out

to
Cybercafe. Just now lucky. Good weather. Got a wifi connection again and
will try
few times if necessary to reply.

OK. I understand a lot better now and I'll try follow up those links.

Sorry abt the Notepad thing. I think at the time I had, like now, a fluke
wifi
connection and tried to squeeze in as much as possible. The connection
usually
lasts only 15 min's but today it's been holding for a while. We'll see.

For anyone interested, the Notepad error occurs only when (1) text file size
exceeds abt 30K and (2) when the ".LOG" function is enabled (auto date/time
insert). There is no error when (2) is not at top of file.

Thanks again,

--
Ted...
