![]() ![]() ![]() EFS is the built-in file encryption tool for Windows file systems. While other defensive strategies should be used, and encryption isn’t the correct countermeasure for every threat, encryption is a powerful addition to any defensive strategy. Even persons who are authorized to access the computer and its file system cannot view the data. Encrypted files can be protected even from those who gain physical possession of the computer that the files reside on. Any individual or program that doesn’t possess the appropriate cryptographic key cannot read the encrypted data. (Windows XP Home doesn’t include EFS.) EFS enables transparent encryption and decryption of files by using advanced, standard cryptographic algorithms. The Encrypting File System (EFS) is a component of the NTFS file system on Windows 2000, Windows XP Professional/Windows Vista/Windows 7, and Windows Server 2003/2008. There are so many data recovery software in the market and this problem is easy to solve if you have not written new files to the partitions, but few data recovery software has this ability to recover NTFS encrypted files, you need professional EFS data recovery software. You may also format a partition and forgot to backup some important files, so you have to recover files from the formatted partition. Data losing is common problem for all of us, for example, you may deleted files mistakenly and need to recover the deleted files.
