Is System.IO.File.Delete function secure?

@agowa338 commented on [Fri Jun 28 2019](https://github.com/dotnet/dotnet-api-docs.de-de/issues/31)

Hello, the documentation does not mention if using this function is secure in the sense of plaintext data being effectively deleted from disk, or if it just removes the file descriptor.

Also the function File.Encrypt is lacking this kind of information. Does it create an encrypted copy of the file or does it actually overwrite the plaintext on disk, so that it cannot easily be restored afterwards.
