Question

I didn’t find any example on google… Can anyone show how it works? And when folders and files will be encrypted how to decrypt them?

FileAttributes Enumeration

Answer 1

The FileAttributes.Encrypted flag tells you whether a file or folder has been encrypted by the NTFS file system. This option is available to users by right-clicking a file, selecting Properties, then clicking the Advanced button. There is an option “Encrypt contents to secure data” which is what the FileAttributes.Encrypted flag corresponds to.

You can use the File.Encrypt / File.Decrypt methods to encrypt or decrypt a file or folder. Note that you can only decrypt something that was encrypted by the current user.

You can use the System.IO.File.GetAttributes method to get the FileAttributes from a file.
