A Bin is a specially made basket for certain stockpiles. A bin can be made from one wooden log at a carpenter's workshop or three bars of metal at a forge. Bins make it possible to store lots of objects into one tile of a stockpile. A stockpile without a bin will likely fill up fast, leaving any remaining items where they are to get in the way.
Stockpiles that use bins are ammo, armor, bars/blocks, cloth, coins, finished goods, gems, leather, and weapons. Food stockpiles use barrels instead of bins. Other stockpiles do not use anything at all.
The number of items that fit in a bin varies on the item type, for example 10 bars/gems or 100 bolts fit in one. See the Weight article for more information on container capacity.
Bins also save time when hauling goods to the trade depot, as a bin marked for trade will be carried along with all its contents.
See stockpile for more information on how things are organized with bins.
If you have a bin that will not be moved to any stockpile, check the contents to make sure that some stockpile will accept that mixture of items. Dwarves will not sort items from bins at the Trade Depot or on the ground. If you have a bin with mixed contents which you wish to have sorted between two or more stockpiles, you must first make a temporary stockpile which accepts all types. Then change the settings on the temporary stockpile to force out the items which you want moved to another bin. Then finally destroy the temporary stockpile to move the now-sorted bin.
To see the contents of a bin (or barrel), use the key and then . Once there, use & to scroll up or down the contents, and (again) if you wish to view that item specifically.
