Pwscf output files?

In my local machine, pw.x generates output files besides the standard output:
pwscf.pot, pwscf.rho, pwscf.wfc
unless I reuse the tmp directory.

However, in lonestar, it genrates,
pwscf.md pwscf.oldrho pwscf.pot pwscf.rho pwscf.save pwscf.update pwscf.wfc

For sure, I transfer all of the possible files from the remote machine.
