Hi how do you duplicate items and if you know can you duplicate lockpicks..

To duplicate items just equip your bow and about 30-40 arrows, (no more or your game may freeze) draw your arrow back but don't fire it. Now go to your inventory and press B on the arrows 4-5 times (it will come up with a message), then click on the desired item and drop it for instance lock picks. Go back to the game and you'll have the num of items you dropped of the num of arrows you have.
You can clone pretty much everything apart from quest items and usually weapons, but you can clone staffs!!!

You can duplicate most anything. Be careful about lockpicks because the will tend to freeze up your game or make it go slow for a while. All you need to do is to get about 30 arrows and a bow. It does not matter which level they are. Now just pull back the bow string and hold it. Now go into your inventory and press "A" on the arrows twice, it should say "You cannot equip items while attacking," that doesn't matter. Now go to the item you want to duplicate and drop it. It is kind of like the arrow shoots the item and splits it into a lot of items. Now pick them all up. You should have a lot of the thing you want to duplicate. It is simple.

Well since they have already answered most of the question by tellin ghow to dupe, ill tell you one thing that I found out isnt dupe-able. Daedric armor stuff is not dupe-able. Especially the helm...which sucks becuase thats hardest part to find.
