Hi all,
I am totally surpriced!
In my host (win7) I have many EFS files. I move them (with the shared folder) to the guest (win 7)... and I was totally surpriced that the guest read them as they are!
The EFS attribute is still there, the file is blue!
At begin, I thought the EFS attribute was removed by moved it to the shared folder... but no, it's still there!!!
Since EFS is based on the certificate and the Windows Profile, so, how that is possible?
The host and the guest are two totally different S.O. (even they are Win 7 both)!!!

Re: How VirtualBox handle EFS files
VirtualBox shared folders present a very simplified file system implementation, just enough to read/write files from/to the guest. Many applications do not work properly when using shared folders, because they expect advanced features, like file locking or access controls, which don't exist for shared folders. As for the blueness of the file, maybe you need to refresh your Explorer?
Bottom line is that if you want to honor Windows specific features, use Windows specific filesharing.

Re: How VirtualBox handle EFS files
Hi,
nope, the GUEST reads the EFS files exactly chipred just like they in the HOST.
It's something I cannot understand, tecnically impossibile, since the EFS files crypted in the HOST are encrypted by the USER-PASSWORD-CERTIFICATE of the HOST and the GUEST should not recognize them!
But, the GUEST read them with the EFS attribute, perfectly... I don't understand!

Re: How VirtualBox handle EFS files
Since Windows is involved at both ends, I suggest that you ask this question on a Microsoft forum.
VirtualBox works at a hardware level (sectors or packets), where higher level file permissions and encyryption issues are not relevant.

Re: How VirtualBox handle EFS files
It's not the guest who is reading the files, it the Virtualbox process started by the user with the rights of this user. Therefore it has access to the files.
