Does mv on a FAT filesystem actually rename or does it copy and delete?

Typo of course, I meant 'mv file1 file2'.

Thanks for the answers so far but to re-emphasise why I asked the

    I know that mv of a file in a directory on a Linux type filesystem
    will just write the new name of a file in the directory without
    moving the data/contents of the file.

    However in different circumstances (e.g. across filesystems) it
    *can't* do this and has to copy/delete.  I was just asking if
    anyone knows if 'mv file1 file2' on a VFAT (i.e. not native Linux)
    filesystem does the 'easy' thing (copy/delete) or not.
