Say you have three files open in Adobe Illustrator, but you exit out of the program. Is there a way that you can have those three files opened back up when you open up Illustrator again? Similar to how most text editor programs are set up -- so when you open up the program again all your last stayed-open files are there.

Also, does anyone know what the terminology for this saving-behavior is? State-saving? Googling to find the answer is difficult within the sea of Illustrator 'saving files' questions.
