BitLocker To Go is BitLocker Drive Encryption on removable data drives. This feature includes the encryption of:
USB flash drives
SD cards
External hard disk drives
Other drives that are formatted by using the NTFS, FAT16, FAT32, or exFAT file system.
Drive partitioning must meet the BitLocker Drive Encryption Partitioning Requirements.
As with BitLocker, you can open drives that are encrypted by BitLocker To Go by using a password or smart card on another computer. In Control Panel, use BitLocker Drive Encryption.
