why my empty cdr file size is so large 7 mb

Check for unwanted color styles and/or symbols saved with the file. Remove it and see if the size is reduced. X6 onwards versions take care of these issues  automatically.

The best way is to see the file, maybe you can upload to a free storage servcie, such as wetrasfer.com or dropbox
