I was facing this issue of unsaved Excel files. While searching for the right solution, this article came to my consideration. After reading this, I tried to restore unsaved Excel file via MS Excel inbuilt utility but failed to recover the files. Then, I checked my previous version as mentioned in this article, but unable to find any session. Lastly, I read somewhere that unsaved files are stored in temp files, only when you haven’t closed the system. But due to sudden power loss, my system got shut-down. So, I am in big trouble, I really want my Excel worksheets at any cost. Is there is any other solution to recover unsaved excel file?
