The backpack module adds bags that render on your character when equipped. They include item sorting, slot memory, a search bar and a security lock, and you can expand them with functional upgrades. Look up every backpack and upgrade recipe in Not Enough Items (NEI).
Organizing the bag
1. Craft a backpack using the recipe shown in NEI and equip it. It appears on your player.
2. Use the sorting function to tidy the contents.
3. Set slot memory so specific items always return to the same slots.
4. Use the search bar to find items quickly in a full bag.
5. Turn on the security lock if you play on a server and want to keep your gear protected.
Choosing upgrades
Each upgrade suits a different playstyle. Pick the ones that match what you do most:
- Stack: raises how much the bag can hold. Use it for bulk mining trips.
- Inception: expands capacity further. Use it for long expeditions.
- Magnet / Pickup: pull nearby drops in and collect them automatically. Useful when clearing mobs or digging.
- Feeding: feeds you from the bag's contents so you do not have to stop and eat.
- Crafting: lets you craft directly inside the bag. Handy away from base.
- Void: gets rid of unwanted items. Use it to stop cobblestone from filling the bag.
- Everlasting: protects the backpack itself. Get this early so you do not lose your gear.
A solid starting setup for mining is Stack, Pickup and Void together. Add Feeding and Crafting once you start spending long stretches away from home.
