sure they do. The *igkN files are removed at the end of the
calculation, irrespective of wf_collect. The *wfcN files are
removed if wf_collect=.true. after the wave function is collected
to a single (per k-point) file ; they are left where they are (i.e. in
the directory containing the *.save/ directory) otherwise.
Of course, assuming that the code does not crash before
the end of execution.
