Copying an Encrypted Folder or File The following explains the procedures and limitations for copying encrypted folders or files on the same volume and from one volume to another. To copy a file or folder on the same computer from one NTFS partition in a Windows 2000 location to another NTFS partition in a Windows 2000 location. Copy the file or folder as you would an unencrypted file. Use Windows Explorer or the command prompt. The copy is encrypted. To copy a file or folder on the same computer from an NTFS partition in a Windows 2000 volume to a FAT partition. Copy the file or folder as you would an unencrypted file. Use Windows Explorer or the command prompt. Because the destination file system does not support encryption, the copy is in clear text. To copy a file or folder to a different computer where both use the NTFS partitions in Windows 2000. Copy the file or folder as you would an unencrypted file. Use Windows Explorer or the command prompt. If the remote computer allows you to encrypt files, the copy is encrypted; otherwise it is in clear text. Note that the remote computer must be trusted for delegation; in a domain environment, remote encryption is not enabled by default. To copy a file or folder to a different computer from an NTFS partition in a Windows 2000 location to a FAT or NTFS in a Windows NTŪ 4.0 location. Copy the file or folder as you would an unencrypted file. Use Windows Explorer or the command prompt. Because the destination file system does not support encryption, the copy is in clear text. Note If your original file was encrypted, Microsoft recommends that you use the File Properties, Advanced option to confirm the status of the destination file. Moving or Renaming an Encrypted Folder or File The following explains the procedures and limitations for moving encrypted folders or files on the same volume and from one volume to another. To move or rename a file or folder within the same volume. Move the file as you would an unencrypted file. Use Windows Explorer, the context menu, or the command prompt. The destination file or folder remains encrypted. To move a file or folder between volumes. This is essentially a copy operation. Review the previous section, Copying an Encrypted Folder or File.

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi everyone, Quick (and perhaps easy?) question for the MS folks. If you have a file on an NTFS volume that is encrypted (with EFS) and you transfer it to a fat32 partition what happens? What happens if you copy the EFS file from one NTFS volume to another? I am going to guess that in the 1st case it decrypts the file (not sure). I am pretty sure that in the 2nd case it retains the encryption. Can anyone quickly verify? I don't have a fat32 partition to test on. In the meantime I will try out the 2nd scenario and you are welcome to mail me off-list if you are curious (unless someone answers it on list). Thanks guys (and ladies of course). Cheers, Leon -----BEGIN PGP SIGNATURE----- Version: PGPfreeware 6.5.8 for non-commercial use <http://www.pgp.com> iQA/AwUBPD0RqtqAgf0xoaEuEQJiZwCgw7TNQs9wVbIZdxAdSZGR8J6D3IoAoNZz SUCaNmqheFn+HZIPhSYY+Btp =Ptbl -----END PGP SIGNATURE-----
