.tex file, I'm pretty sure has become a binary file. It begins with this:
\%PDF-1.5 \%ÐÔÅØ 6 0 obj << /Length 1662 /Filter /FlateDecode >> stream
and there's a lot of odd symbols. I'm using TeXstudio to compile my documents and when I click the 'view' button I get the document as it looked previously so I'm assuming all the data is still there, but is there any way to get this back into a latex form so I can continue actually using it, or do I have to begin from scratch?
