Editting attachments

I emailed a document to myself and then opened the email. When given the option of 'editting ______' or downloading it. I downloaded it and then made several changes and saved it. I now cannot find it anywhere. If I go into the original email obviously it has the original document saved in active view, there is nothing in Skydrive, I can't find anything saved on the computer itself. I was thinking that Active view was cloudbased and I saved it to there but obvioulsy not. Can anyone tell me where I may have saved it????
