This is a known problem. It is the java.net.URL class that is doing
it. When the listFiles routine calls the SmbFile constructor the name
is passed to the URL class which is trimming the space. There are
other characters that are known to cause problems like this such as #
at the end of names. There's not much we can do about it other than to
dump the java.net.URL class at some point but that would require a
Note that if you use an SmbFilenameFilter you can get to the
un-trimmed filename. But I don't know if that will help you because I
don't know if you will be able to create an SmbFile instance with it.
