it is a temporary file with an 'internal' format.
please check with the documentation (Doc/INPUT_PP):

  !      The two steps can be performed independently. In order to perform
  !      only step 2), leave namelist &inputpp blank. In order to perform
  !      only step 1), do not specify namelist &plot
  !
  !      Intermediate results from step 1 can be saved to disk (see
  !      (variable "filplot" in &inputpp) and later read in step 2.
  !      Since the file with intermediate results is formatted, it
  !      can be safely transferred to a different machine. This
  !      also allows plotting of a linear combination (for instance,
  !      charge differences) by saving two intermediate files and
  !      combining them (see variables "weight" and "filepp" in &plot)

if you need even more details about the contents of this file,
you have to read the sourcecode. there have been plenty suggestions
of how to locate the corresponding file for a specific feature posted
here recently, so i'll skip that. note, that the format of intermediate
files may be changed between different versions of the code
(in order to accomodate new features).

cheers,
    axel.
