opening excel in yahoo email

I have a friend who sent himself an excel file to his yahoo email account at home.  He then went home and opened the email and double clicked on the attachment which was the excel file.  He did some changes to the excel file and clicked on save.  He closed out excel and then started a new email and wanted to email himself back the excel file he just worked on and send it to his work email.  Problem is he has no idea where the file is.  Does yahoo open a temporary excel program or something like that?  Is the file somewhere on the computer?

Yes, when user opens the attached excel file, i guess he worked on temporary file. it might be in AppData folder or temporary Internet files folder.

In Internet Explorer click Tools menu, Internet Options then click "Browsing History" click on Settings, and in the resulting dialog click on View Files.
If it hasn't been too long, your file should be there. copy it to a different folder on your machine asap
