Quantum Bags
by xJenny69
Quantum Bags is a Forge storage mod that adds bags with very large item capacity for a single item type.
What it does
Each quantum bag stores one item type and takes a single inventory slot. Four tiers hold 512, 4096, 32768 or 262144 items of that type, and config options change how many each tier stores. Right-clicking with a bag in hand cycles through three modes: inert, filling and sucking. Filling automatically tops up half-full stacks in the inventory, while sucking pulls matching items from the inventory into the bag. The config file is saved in the world's serverconfig folder as quantumbags-server.toml. Quantum Bags runs on client and server and is published for Forge 1.20.1 only, with the latest file 0.0.4 released on 2025-05-17.
