Changes not Saved in Project

I have a project IMIS.aspr. I moved the project to another directory and attempted to open it. All changes that I made were gone.
They still appear in the original project folder. I need to move the project file to another directory and retain changes. How do I do this. <img src='https://asprunner.com/forums/file.php?topicimage=1&fieldname=question&id=4205&image=1&table=forumtopics' class='bbc_emoticon' alt=':(' />
