help gettin rawfiles into one project

I’ve been searching high and low to find out how to restore a saved project. My song is saved as “raw-files” named “d00”, “d02” and so on, and there are about 500 files that i can not open as a complete project. I have tried to open all the files in one window, but when I try to emerge the files into one line, they are just a complete mess.
I would like to have the bass on one line, and the drums on another, but I cant seem to find out how to manage?
I have 8 different maps and each-one contains over 100 small files with sounds. What can I do to open this project again? Or do I have to start all over again?
I will never close another audacitywindow again until the song is complete and saved as a .mp3 :blush:
