Technically, this is a Windows XP problem, but it was made by Ubuntu, so thought I'd ask it here to make sure the Linux geeks see it.
I've been playing with Ubuntu for a few days, installed it to disk and used it. I liked it, had no problems with it really, nothing I couldn't figure out with 30 seconds on Google. But I just, ehh, didn't find anything about it that is a big advantage to me over Windows.
So I got rid of it now, fixed my MBR and deleted the partitions, all back to a normal single boot XP Pro SP2 now. Just one leftover little thing I can't get rid of. When using Ubuntu, I mounted my Windows partition so I could browse some files on it from Ubuntu, and am now left with this folder and file on the root of my Windows drive. It won't let me delete it. The folder was originally named .trash-mike, I tried renaming it, which it let me do, when I couldn't delete it, still can't delete it, and it won't let me rename it back to its original name. The file inside the folder I can't even rename.

I could just leave em and ignore them, they have no size, but just wondering if anyone knows how I get rid of these.
