Hello there,

I am sure he pulled out the data from ... one of the file.
he blocked my veiw

How can you specify what he did & be so sure about it, when you couldn't see anything!.

Plus if I was the one with such a knowledge, then I wouldn't want any
of my other associates knowing my secret capabilities, unless you are a
very close friend, but then in this case I wouldn't hide anything from you.

So I think that the best think for you to do is to persuade your friend to
show you how he did it, then you can come and tell us.
