I would like to copy some pdf files.  I realised that the files were being
renamed during download so when for a usef defined structure with the
following option:

%h%p/.%t

Now this seems to do what I want but after 37 files have been copied it starts
re-using the file numbers.

Here is one of the lines from the log

14:24:20	122253/122253	---M--	200	added ('OK')	Application/pdf
date:Sat,%2007%20Jan%202006%2014:04:31%20GMT
www.historicaldirectories.org/exe/wwt.dll/pdf?fn=e:\hdapps\00009zoc.pdf
C:/My%20Web%20Sites/1914b/www.historicaldirectories.org/exe/wwt.dll/-13.pdf
(from )

The file I am requesting is 00009zoc.pdf and ideally I would like to preserve
this file name, if I can't then some numerical sequence (in the same order as
requested) would be fine.

Is there a better way of doing this.

Thanks
