Reading Maps back in to game array?

Hi! I know how to read files and have succesfully read my saved map back in to my game array. The question is, I need to be able to have the user select what map to load from a directory where many maps are saved. each maps name is given by the user so I would need to be able to select a map to load from a directory and load it.

I'm not using MaxGUI just th standard graphics 800,600 mode.

Any help would be appreciated. :)
