Therefore, you can rename an encrypted folder or file in place, and it remains encrypted. If you rename a folder or file, the encryption attribute is unaffected. The syntax is similar to that for the COPY command. XCOPY, however, uses the /G switch for this functionality. The XCOPY command also supports copying to non-EFS-capable volumes. You can use the /D switch to copy an encrypted file to a non-EFS capable volume, but the file loses its encryption. The COPY command used in a command console has been modified to support encryption.
In this case, the file remains encrypted in the backup set. An exception to this is when you use the Backup utility to back up the files to a Backup file (BKF) on a FAT volume. Windows displays a prompt indicating that the files cannot be encrypted and gives you the option to copy or move the files anyway, losing encryption. ♦ Copying and moving encrypted or unencrypted files to FAT volumes. The COPY console command causes the destination file to be encrypted, but the MOVE command does not because it simply renames the file. This applies to copies on the same computer and to a remote computer that supports encryption. The folders or files are encrypted when copied or moved through the Explorer interface. ♦ Copying and moving unencrypted folders or files to encrypted folders (NTFS volumes).
In a domain environment, the destination computer must be trusted for delegation - remote encryption is not enabled by default. If you are copying to another computer, the objects are encrypted only when the destination computer permits encryption. The copies are encrypted regardless of the encryption attribute of the destination folder. ♦ Copying and moving encrypted folders or files to unencrypted folders (NTFS volumes). The following list summarizes the effect of the encryption attribute in copying, moving, and renaming objects: As with compression, a folder's encryption attribute also has an effect on the files that you copy or move between encrypted and non- encrypted folders or files and folders that you rename.
