How to convert a data file back into Hype?

Hi,

I recently got a new laptop and the Hype file I was working on converted into a data file once I backed my laptop up. Does anyone know how to turn the data back into my Hype?

What do you mean with data file? Your .hype file got compressed or has a new file-extension?

If you mean the document recovery that is explained here:
