RENAME--Notes

Using wildcards with RENAME

You can use wildcards (* and ?) in either filename parameter. If you use    
wildcards in filename2, the characters represented by the wildcards will be
identical to the corresponding characters in filename1.

RENAME will not work if filename2 already exists

If, for filename2, you specify a filename that already exists, RENAME
displays the following message:

    Duplicate file name or file not found
