In Notepad++ or what ever editor you use.
open loot.ini, use "find and replace" to replace the word "ignore" with the word "destroy".
Now everything that used to be left on the corpses will be destroyed, including no drop. Of course if they are lore then you will have to go through and destroy all that are on the looting toon.
I made a hot key for it.
LOOT DESTROY
/lootdestroy
/destroy
This way I just pick up the item, or stack of items, and click the button with the item on the cursor. It's marked destroy in the loot.ini file and also destroyed. If you are confident you can turn on fast destroy in Options. Then you can run through things quickly. Just be careful what you have on your cursor.. it will be gone!
I know people use the "/hidecorpse looted" but for me the "Loot destroy" is my solution of choice.
