that the file object is a SpooledTemporaryFile, so if what you want to
do is copy the format to another file, use :method:`copy_format_to`
instead for performance.

path to the temp file

the same as that used in the library. Note that using
this means that repeated calls yield the same
temp file (which is re-created each time)
