How to input a data file on a disk with mouse in OpenGL or Glut program?

[shutian]

I use OpenGL and Glut to display large amount of seismic waveforms. Could you tell me how to input a disk file with mouse directly to the program that is running.
examples are greatly helpful.
Thanks in advance

There isn't anything in OpenGL or GLUT to do that.
I use the functions in <stdio.h> to do all my file loading and saving.
