What does "dir /x" show? The "/x" option should give you the 8.3 version of
the name. That may be being matched by the wildcard.

For what it's worth, this behavior is not limited to Samba servers. I have
the
exact same problem using standard Microsoft servers. Dir EC05*.* might
return a
file named EC11*.* which is also visible if you Dir EC11*.*.

The main difference is that my problem doesn't seem to be reproducible like
yours. During the course of a month we generate several thousand of these
files
which are processed then archived and deleted. The names are all unique,
containing date/time stamps. In the course of a month maybe 10 of these
files
will be affected as you describe. We have modified our code to monitor for
this
situation and give warnings.

That's exactly the issue. The SMB/CIFS wildcard matching
algorithm matches both short and long names.
