What happens when files are moved or copied?

All files and folders that are created in a folder marked for encryption are automatically encrypted. Moving and copying encrypted files and folders can change the encryption state of the file or folder, depending upon the situation.

When moving or copying files, keep the following rules in mind:

■ If you move a file from an unencrypted folder to an encrypted folder, the file inherits encryption from the destination folder.

■ If you copy an unencrypted file to an encrypted folder, the copied file is encrypted. If you copy an encrypted file from an encrypted folder to an unencrypted folder, the file remains encrypted.

■ If you copy an encrypted file from an NTFS volume to a file allocation table (FAT) or FAT32 volume, the file becomes unencrypted. If you copy a file from a FAT volume to an encrypted folder on an NTFS volume, the file becomes encrypted.

■ When you encrypt a folder, all files and subfolders that are added to the folder in the future will be encrypted when they are added.

What Is WebDAV Server?

Introduction Files that are stored on remote servers that use EFS are vulnerable to packet sniffing because they are sent unencrypted from server to server.

One solution to the problem of files being sent in unencrypted format over the network is to implement Web-based Distributed Authoring and Versioning (WebDAV).

What is WebDAV? WebDAV is a set of extensions to the Hypertext Transfer Protocol (HTTP)

protocol that allow users to remotely manage and manipulate files on remote file servers. When you use a WebDAV location when implementing EFS, the file is encrypted locally on the client computer and then sent in a raw encrypted format to be stored on the server. This prevents packet sniffing when files are being transmitted from a client computer to a remote server.

Since WebDAV is an extension to the HTTP protocol, access to a WebDAV folder is achieved by accessing a Web server running Internet Information Services (IIS). WebDAV is a popular solution for sharing files and collaborating on files over the Internet because it uses HTTP port 80 and existing internet applications such as Windows and Microsoft Internet Explorer.

Note To reduce the attack profile of IIS 6.0, WebDAV is disabled by default on Windows Server 2003 and must be manually enabled.

Additionally, since WebDAV is integrated into IIS6.0, it can take advantage of permissions control in IIS 6.0 and access control lists on NTFS.

How to use WebDAV

To open a location that has been enabled for WebDAV, use Internet Explorer to manually open the location, and ensure that the Open as Web Folder option is selected in the Open dialog box.

The following illustration shows the Open dialog box in Internet Explorer. Notice that the Open as Web Folder option is selected.

When a WebDav location is opened, a user with the correct permissions will be able to create, delete, modify, lock, and encrypt files at the WebDAV location.

When you move files and folders within the same partition, they retain their permissions

* When you move files and folders to a different partition, they inherit the permissions of the destination folder

Introduction When you copy or move a file or folder, the permissions may change depending on where you move the file or folder. It is important to understand the changes that the permissions undergo when being copied or moved.

Effects of copying files When you copy files or folders from one folder to another folder, or from one and fo|ders partition to another partition, permissions for the files or folders may change.

Copying a file or folder has the following effects on NTFS permissions:

■ When you copy a folder or file within a single NTFS partition, the copy of the folder or file inherits the permissions of the destination folder.

■ When you copy a folder or file to a different NTFS partition, the copy of the folder or file inherits the permissions of the destination folder.

■ When you copy a folder or file to a non-NTFS partition, such as a FAT partition, the copy of the folder or file loses its NTFS permissions, because non-NTFS partitions do not support NTFS permissions.

Effects of moving files To copy files and folders within a single NTFS partition or between NTFS and fo|dere partitions, you must have Read permission for the source folder and Write permission for the destination folder.

When you move a file or folder, permissions may change, depending on the permissions of the destination folder. Moving a file or folder has the following effects on NTFS permissions:

■ When you move a folder or file within an NTFS partition, the folder or file retains its original permissions.

■ When you move a folder or file to a different NTFS partition, the folder or file inherits the permissions of the destination folder. When you move a folder or file between partitions, Windows Server 2003 copies the folder or file to the new location and then deletes it from the old location.

■ When you move a folder or a file to a non-NTFS partition, the folder or file loses its NTFS permissions, because non-NTFS partitions do not support NTFS permissions.

Effects of copying and moving within volumes

To move files and folders within an NTFS partition or between NTFS partitions, you must have both Write permission for the destination folder and Modify permission for the source folder or file. The Modify permission is required to move a folder or file, because Windows Server 2003 removes the folder or file from the source folder after it copies it to the destination folder.

The following table lists the possible copy and move options and describes how Windows Server 2003 treats the compression state of a file or folder.
