Encryption Question

I have a Windows XP Pro SP2 workstation that I use for email and accounting. I also have a laptop
that I synchronize to the workstation when I travel and then synchronize the workstation to the
laptop when I get back. I would like to encrypt the data on the laptop but not on the workstation.

I use XCopy to copy data between the workstation and the laptop. (Windows networking -- no domain
controller) I use the /G option (Allows the copying of encrypted files to destination that does not
support encryption.) when copying to the workstation from the laptop. This works fine for files.
But if a directory on the laptop are encrypted XCopy fails saying it cannot create the directory.
So I have had to walk the directory tree and unencrypt each directory while not unencrypting the
files under it. While this allows XCopy to copy undated files to the workstation it means I have to
remember to encrypt any new files on the workstation as they don't get the encrypted attribute from
the parent directory.

Is there anyway around this? Anyway I can keep the entire tree encrypted on the laptop and not on
the workstation and still copy updated files to the workstation?

How about storing the data in strong password protected ZIP files ?

WinZip v9.0 Sr1 supports 256 bit AES encryption.

Two reasons:
1. XP encryption is transparent to all applications. Once the files are on the laptop everything
works. I don't think that is true for a zipped directory tree.
2. Updating would be a problem in either direction.

Transparent maybe, problematic -- yes. As you have seen.

Updating would not be a problem. Extract file edit and then move file back into ZIP file.

Are you able to copy these files using r. click > copy and then paste.
Also, are you running xcopy on the desktop computer? If so this would
explain it. Easyist "work around" would be to exprot the encyption
certificate from your laptop to your workstation. This 5 part guide
should explain every thing you need to know.

As another responder commented, be sure you're running the xcopy from the
laptop. The files must be decrypted on the laptop (where your EFS
certificate/key reside) before they can be transported. You didn't mention
using other xcopy switches, but using the "/s" switch with xcopy will also
copy over the sub-directories (Example: "xcopy /s /g <source>
<destination>").

Thanks.

Have you considered using window's offline files feature? You can set
the offline cache to be encrypted I do believe...

The command line is:
xcopy C:\users\shared U:\Users\shared /c /f /g /d /e /k /h /y /z

The /e switch copies all directories including empty ones.

The problem occurs any of the directories are encrypted on the notebook and they exist on the
workstation. The xcopy command throws an error saying it cannot create the first one and stops. I
am running the command from the notebook. If the directory on the notebook is not encrypted
everything works fine.

I don't want the directories/files encrypted on the desktop.
