Recently, I loaned my flash disk to one of my friends, who had Mac OS. He copied a file on it, whose name included a backslash (\).

The flash disk is NTFS formatted. Windows does not allow such filenames, and neither opens the file, nor deletes it, nor lets me delete the file.

There are naive approaches to this problem, like:

• Formatting the flash disk;
• Giving it back to my friend and asking to rename it;
• Loading into some live Linux and renaming it.

However, I'm looking for something more clever, like a program that can do the trick under Windows.

PS: There's a tool called NTFSWalker which can browse the MFT records of the NTFS, but is unable to make any changes to them.
