I can't copy all the folders and files on one of my flash drives to my hard drive because one of the files is corrupted. I've tried to delete the file, even the folder, and re-copy it, but I can't delete it and I can't copy over it, because it's corrupted. I even went into "Safe Mode" in Windows XP Home Edition, and tried deleting the file and/or folder then. No luck. Same reasons. I want to clean up this Flash Drive because the Flash Drive is supposed to be my copied versions of important files and folders, and when things get corrupted on my hard drive, I then use the Flash to backup files and folders. So, it's important that the Flash Drive be correct. How this happened, I don't know, but I have another backup that can correct the files on the Flash, if only the Flash would allow me to delete files and/or folders so I can copy the originals onto it. Until I delete that one corrupted file, I'm unable to copy the original over the corrupted file, and unable to replace the corrected folder in todo. Please advise. (Keep in mind, I did try to delete and copy over in "safe mode" with no luck. I though about going to regedit, but how do I find a particular file in its folder in XP's registry?
