These files completely alter the loot lists for animals, plants, chests, and NPCs.
You will have the same chance to find any item at level one as you will at level fifty. It will be extremely unlikely to see a typical bandit using any glass or ebony armor. Most common bandits will wear tier one or tier two armor with a small chance to have tier 3 and a smaller chance to have tier 4 armor. The higher the value the more rare it will be.
Each time you harvest you will gain a random amount of items and ingredients as you would logically expect. So a plant with three blooms could yield from zero up to three blooms. a plant with many blooms like the mountain flowers can yield many more
Animals each have a random loot table that will never include gold coins(with the exception of dragons because everyone knows dragons hoard gold)
You can find any type magical items as well but over all the frequency of magical items found in bandit stashes will be a rare thing indeed.
Overall I feel this gives skyrim the feeling that you are stepping into a living world that has been around a while rather than watching a world form and revolve around your every action.

The base game is covered and there are sub-files for use with each of the official DLC.
An additional file to use if all DLC are loaded

Uninstallation:
You want to do WHAT?!?!!
OK fine, be that way. Just delete the files or uninstall via your mod manager of choice.
There is no risk of long term damage to your save, but you may find a few bandits that have no loot to take after you kill them until the tables reset(should be 72 hours in game time)
