Stuck with this

I am almost done with my blog now.. but now I moved up to the ranking and comment section. My entries are saved in directory 2005/December/December-2005.txt for Dec Archives.

Now my problem is ... I have rank.txt and comment.txt on seperate folders from entry folders. If someone rank/comment on each entry, I don't know how to relate the comments to that particular entry... you know what I mean? So when the surfer browse my blog they read a particular entry and see that entry's comment.
