Hello, I completed a lot of work on a pages document then went to change the name (I obviously didn't know how to do this properly) and went to 'get info' and changed the name in the box. The hide extension box was clicked but again I didn't realise what this meant.. Now the file won't open in pages and appears as a folder with a 'JPEG' of the first page of the document. How do I change it back so I can read and edit the full document again.. I've read in some places that I shouldn't change the name when hiding extensions as I can lose it.. I just really hope there's some way of reversing as it was a lot of work!
