True or False? A file copied from a full disk-encrypted hard drive to a USB memory stick always stays encrypted.
True
False
The copied file is a new file and its encryption status is usually lost.
EDIT:: What a smart answer !!! let's say you have a hard-disk encrypted with latest encryption algorithm and you simply just by copying an encrypted file to a usb the encryption is LOST!!!!?? really??!??? ::COMMENT:: This specific issue of encryption has some blurred information and some contradictions. Encryption keys need to be present in order for decryption to take place to begin with. Yet in many references is stated that moving encrypted files/folders to non-encrypted volumes will remove the encryption.
::COMMENT:: But how do you explain data being backed up in encrypted form?
::EDIT:: The answer has been changed to false: This is not ALWAYS the case. In windows 10, EFS may be used on both FAT32 and NTFS volumes. This is not the case in windows 7: Copying a file from a bitlocker encrypted NTFS drive to an unencrypted USB FAT32 drive will remove the encryption. Notice the question specifically states: "ALWAYS" Which means this would have to work on ALL editions of windows, mac, and linux OS's.
::EDIT:: I don't understand how this could possibly be so confusing. All versions of encryption I've seen, whether LUKS or TrueCrypt, require decryption to take place before their partitions/folders can be mounted and files assembled into a meaningful form, otherwise the only thing a user sees is gibberish. Once you have successfully decrypted the data, it stays decrypted until either partition/drive unmount or in the case of SED power-off. Therefore, assuming you're in the desktop copying files to a USB drive, what you are copying is already decrypted. Why would it stay encrypted?
