BitLockerÂ Drive Encryption is a data protection feature that integrates with the operating system and addresses the threats of data theft or exposure from lost, stolen, or inappropriately decommissioned drives and computers.
New files are automatically encrypted when you save them to a drive encrypted by BitLocker. However, if you copy these files to another drive or a different PC not encrypted by BitLocker, the files are automatically decrypted.
BitLocker To GoÂ is BitLocker Drive Encryption on removable data drives. This includes the encryption of USB flash drives, SD cards, external hard disk drives, and other drives formatted by using the NTFS, FAT16, FAT32, or exFAT file systems.
You can choose to unlock BitLocker for a removable data drive with a password or a smart card. You can set the removable data drive to automatically unlock after encrypted when you sign in to Windows.
