How to delete hidden .swap files (.sw?) if there are no changes?

I have near a dozen files where I have both a ".cc and a .h"
open but had a desktop reboot, so all have swap files now.
Just now, I opened them all and found that only 1
pair had any changes that needed to be addressed, but the
others were all 'unmodified'.


Is there a way to have vim automatically delete the swap
files for which there are no changes and no running process?

Alternative, is there a way to tell in a shell that
some correspond to unmodified files so I could pre-delete
them in restarting gvim for all the files?

I don't want to blindly try to recover them, as any that
do have actual changes, I want to know about so I
can write them to /tmp and compare them w/the origs to
see if what the changes are and if they should be kept
(usually should, but occasionally not).

Thanks in advance!
