In older versions of Windows prior to 2016 if you move or copy a file encrypted with EFS from NTFS to FAT32, the file will be decrypted in previous versions. EFS is also older, and has been around since Windows Server 2000, whereas the newer BitLocker solution has been around since Windows Server 2008.ĮFS works at the file system level, and requires NTFS to work. BitLocker is therefore considered to be more secure and preferable, as you can use it to easily encrypt a full volume which will ensure that everything within is encrypted.ĮFS on the other hand requires that you manually enable encryption on a per file or folder basis.
