I had two calendars - one was blank and the other I was using. I recently
closed one of my personal folders as I was not using it. I could then get
only my blank calendar. My working calendar was not gone.

I interpret this to mean a calendar is part of a personal folder. I did a
DATA FILE MANAGEMENT and opened the file I had closed, and my working
calendar was now back.

How can I bring my working calendar to my good Personal Folder, and then
close the other Personal folder?

Thanks, Steve
