What is the best way to save a lot of data?

Question

Hello,

I am creating a program which has a lot of data in it and I am trying to figure out what would be the best way for me to save/load this data once the program closes/opens.  Let me first describe the program, It has a list box on the left and a rich text area on the right.  Depending on the selection in list box, the rich text area will be populated with text of different font, size, etc...

So since I need to load correct text every time a selection in list box is changed, what would be my best approach towards this.  Rich text is going to have a lot of text in there, lets say about 500-1000 chars in length.  I was hoping to use access database, but this is not a must, only a thought.  I could really use some suggestions for this.

Please feel free to ask me any questions if I wasn't detailed enough.

Regards,
