I woke toda to discover my iPhone 5 documents app was empty

[dvtrv]

I also went online to discover all the hundreds of files I put I in there have gone also.

Can I get these back?

I have/had some very important items in there\.

What can I do?

Many thanks in advance.

What "documents app" are we talking about exactly?
