Two files, never deleted

There are two files in my Memory Stick PRO Duo that have been there since I got it: MEMSTICK.IND and MSTK_PRO.IND. Can I delete these, because they are really annoying and keep moving around the folders and stuff in Windows Explorer.

I think it should be okay. I've completely deleted every last file on my MS' many times and it still runs fine. I think there files the PSP makes when you use it to load saved games.
