Ans :
One of good or bad point of EFS is that its use does not require any administrative
effort and keys are created automatically, if the user does not already have a publics key
pair to use. Files and Folders are encrypted on a single file or single folder basis, each
wit11 a unique encryption key and as they are encrypted uniquely, if you move an
encrypted file to an unencrypted folder on the same partition, the file will remain
encrypted. If you copy an encrypted file to a location that allows for encryption, the file
will remain encrypted.
The EFS is a very transparent in use and user may have encryption enabled without
aware of it.
