File backup (Students) - Mac Stickies Backup
The text and other characteristics of notes in the Stickies application are stored in a file named "StickiesDatabase" in the Library folder inside a user's Home directory. To back up your Stickies, quit the Stickies application to be sure all current notes are saved. Then copy the StickiesDatabase to another location.
To restore your backed-up Stickies, first be sure the Stickies application is not open. Then copy the backed-up file to the same location. Be sure it is named "StickiesDatabase".
