The files are placed in the path indicated by the 'file" attribute
relative to the location of the pvd file itself.

You should try using the Python scripting API to open the files and
write them out. Something like this could work:

for i in range(100):
   r  = OpenDataFile("foo_%s..." % i)
   UpdatePipeline(r)
   SaveData("foo_%s.e" % i, r)
   Delete(r)
