Can anyone help me deleting my files?!

[shahe22]

one day, while I was working on my computer, my operating system crashed!! but well, I have backed my system up, and I knew I can restore it in 5 minutes... but the problem was that I had some important files on drive C: (my system drive) which I will have to delete then restore! [I know I can repair my system.. but I knew it won't be satisfying for me]...
so I grabbed my Knoppix CD (Live Linux, it allows me to run Linux from the CD, no HDD required) and inserted it in my CD drive... well, to make a long story short, I accessed my Hard drive and moved my important files to other drives than drive C: and proceeded with restoring my system (which is Windows XP SP3) but as soon as I log-into my system and went to check the files I moved, I found out that some of them had been renamed and had question marks in their names!! You know that we can't add any question marks to file names on Windows! I didn't know how that happened!! [Please Check attached snapshots]
so when I tried to rename the files I failed.... I ran Knoppix AGAIN and tried to rename or remove them from there and I failed!! I tried to use DOS to remove the directories that contain the files and I FAILED too!!
Thanking god, these files that I wanna get rid of are not so important to me, they're just taking some space...... is there anyway to remove these files without having to Format the partition that have them?? can I even rename them? Any help would be much appreciated...

The reason you cant use question marks in windows is because that's what windows uses to indicate a file that you have deleted but has not actually been removed from the disk yet. I think if you login to windows in safe mode you can access the files and rename them. Someone correct me if I am wrong. What file system are you using on the disk?

I'm using NTFS.. I'll try to login in safe mode and tell u what I ended up with! thanks, I'll get back to you...
