Sure it's possible if you happen to know the format of it, but I have a feeling it's going to be useless information to you even if you do manage to find that out. It seems like it's safe to delete.
Try opening it with a hex editor. That will at least show you if it's a text file or not, and if not it might contain text which a hex editor will display. If you want, you could use my hexview program which you can find in the Articles section in the Source Code category :)
