I know exactly why that is happening and it is
not your fault - MicroSoft f*cked up in a big way.

Something like "dir *token*.*" not only picks up
all files containing "token" in the filename, but
also all files containing "token" in the 8.3 filename.

Take a look at the results of "dir /x", which will
display both the long and 8.3 names of the files.

Normally the 8.3 filenames don't cause a problem
because they are usually just a truncated version
of the long file name, but sometimes there are
incongruities between the 8.3 and long names.

For that reason, you should *never* trust the output
of expressions that use wildcards (* or ?). You can
use the wildcarded expression to generate a list of
files or folders to process, but you still need to
inspect each file/folder on that list before doing
anything with it.

I suggest you try modifying your batch file so that
it checks for a tilde in the filename. If no tilde,
then procede with the rename, else do nothing.
