Hello, I own a laptop with Windows XP on it,

I recently moved some files to my Drive E, with is where I write files ONTO blank CDs/DVDs

After I had written the files to disc, I went to DELETE the ones on the drive
But it won't let me!

Keeps coming up with the following error/MESSAGE -

''Error Deleting File or Folder
Cannot delete It is being used by another person or program.
Close any programs that might be using the file and try again''

Naturally, I close all programs down, so that the only thing open is the folder/drive E.

I try to delete again, but the same message appears!
I also can't RENAME or move them!
They are stuck there, I'm the only user on my laptop, so no one else is using the files/has them open!

I thought I would leave them there and irgnore them, but when I go to write files on CD's, they also write on there! Even though I only highlighted/selected the ones I wanted!

Can someone PLEASE help me?! Getting really annoyed with it all, also went to the official Windows help site, but they won't let me post a message or anything!

Usually quiet good with computers, but can't think of what to do!
I TRIED opening the files and editing so I can resave the file and then delete, but it won't let me resave them!Restart and press F8 to get into safe mode. Delete files and restart again normally this time. I hope that helps you out.
