Sometimes It won't load straight away, so click it again.
You see. Floor | Inventory | Sell NPC | Storage | Guild Storage
With the arrows below them, click on the items you want to sell, etc, use Ctrl to select multiple items, or select all by clicking on the top item of the list, hold shift then select the bottom item.
After you are done, Save it, it will hang for awhile, they are all saved to a notepad in /Data folder.

Good luck.
