Probably a bug and not a case of a missing an option.

Can you share the pvtp and vtp files with me off list? Otherwise, please 
advise me as to how to recreate the behavior with standard sources and/or 
regression test data sets so I can investigate.

Thanks for trying the new reader and reporting the problem!

	Hello,

	I would like to convert (using "File->Safe Data" option) some pvtp file into 
xmf file using the new xdmf file exporter in ParaView trunk. The pvtp files 
were generated while running in parallel using 8 mpi processes, so I have 8 
vtp files for every pvtp file. The pvtp file has a list out all the pieces 
(vtp files).  I also have 30 time steps for the data so I have 30 of the pvtp 
files.

	When I tried to save it out using xdmf3 writer, the collection of pvtp and 
vtp files which are a total of  80MB in size grew to 1023MB in h5/xmf format. 
In another instance, a 817MB pvtp/vtp files grew to 13G when converted to 
h5/xmf file format.

	Is there a compression that I can turn on to reduce the size of the file? Or 
is it something wrong (option not checked) that I am doing that cause the file 
size to increase more than 10 times?

	thanks
	-simon
