Can't move .bin file(s) to Microstudio

[sea otter]

I suppose that a thorough understanding of the manual might clear up my foggy understanding but I'd like to first pose two questions:

1. Why doesn't Microstudio allow to import tracks from files (tracks) already contained in the computer? It seems to default to importing from the CD drive only.

And,

2. Why is it so difficult to move a .bin file from a folder to Microstudio?

I have .bin files which I created using KHPro and exported as .bin to various folders. They are useless if I cannot move them to Microstudio.
