"simple" question

I'm trying to import files but so far no luck.. They're pencil sketches and I'm trying to import them to trace for modeling. Unfortunately, I haven't been able to import anything
( .ai , .eps, .pdf ) so far. I'm ( perhaps ) foolishly assuming that : select import, then select file from the appropriate directory imports a file into one of the four windows? Thanks for your patience...
