Importing partial downloaded files in BitComet

I reinstalled my o/s and now i want to import the files that I partially downloaded with bitcomet in my old computer. Is there a way to start back up where I left off. Suppose I had 90% of a file downloaded, can I still have that since I have the .bc! file?

I’m not really sure. What I did was I copied my entire BitComet program folder (downloads and all) to my backup HD and moved it back to my system HD when my OS wipe and reinstall was complete. It was like nothing ever happened.
