XP Not encrypting my folders and files...
-----------------------------------------

New system, Win XP Pro SP2, 1 GB RAM, all NTFS partitions (no FAT32 format
option available during install).

(1) Encryption Problem.

Not sure if I understand the new terminology but thot that "encrypt" meant

"Convert ordinary language into code" so no one can read it until decrypted.

Well, that's not the case here. When I do my thing, all I get is a font
change
to green for the folder and file names, so on. When I tick and Apply,
"Details"

remains shaded/inactive. There are no compressed files. The folder is in C:\.

I did see the dynamic file transfer pop-up an things hopping from left to
right; but after all that, everything in those "encrypted" folders is still
accessible as usual in my account (which, by the way, was not
password-protected
- but is now).

I subsequently placed a test folder under my account in "Documents and
Settings"
and followed same procedure. It had one file. I did not see the file-transfer
pop-up this time and results were same. I can still access the folder and
file
at anytime without going thru any decryption procedure.

Perhaps I just don't understand what MS means by "encryption" in the context
of this OS. Am new to this issue.

The info on the subject given in Help seems rather skimpy and doesn't really
put

any light on the subject for me. There is no meat in there. So I don't really
know what's going on or what I may be doing wrong.

Can any one clear this up for me please?


(2) Notepad Memory Problem.

This has been bugging me for a long time, since the last XP computer I worked
on. It looks like this is a standard bug or intentional. Whenever a
Notepad.txt
file reaches around 50 KB, a warning message pops up about 'not enuf mem to
complete the operation' yet the file does open ok once I x out the message. I
got 1 GB RAM in here and not many aps installed yet. It's annoying. Is there
a
registry fix for this?

Thanx in advance,

1) This is the way EFS (encrypting file system) is supposed to behave.

The first time you encrypt a file, your computer will try to find a CA
(certificate authority) from which to enroll an EFS certificate. If there is
no CA (which I'm guessing is your case), then your computer will generate
its own EFS certificate. For each file you encrypt, your computer will
generate a unique FEK (file encryption key) and use this to encrypt the
file. Then the FEK is encrypted with the private key corresponding to your
EFS certificate. This blob is bound to the file, and then the file is saved
to the hard drive.

When you log in using the same account you used to encrypt files, EFS
transparently decrypts files as you access them. That's why you're seeing
the behavior--you can continue to work with your encrypted files without
having to go through a manual decryption step. But to all other user
accounts on the system, your files will always appear encrypted--and
therefore useless if someone copies them.

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,
