How can I see changes made in part since last save?

Often, I'll leave Solidworks open on my computer overnight and in the morning, the file name will have an asterisk next to it, indicating that a change has been made since the part was last saved.  Is there a way to see what these changes are?  When I go to close the file, I'm prompted to save and I'm not always sure if I do want to save or not.  Thanks in advance
