Blocky File
by Myitian
Blocky File lets players store the blocks of a Minecraft world as files, then import, export and reload them, and it does so from the client side.
What it does
The mod saves and recovers blocks from the world as files on the computer, and reads stored block files back into a world. Its block palette tools import and export palette data through the clipboard, a file or the blocks in the world, and a configurable block palette map sets how block bits are read. Reloading the configuration file applies changes without restarting the game.
It is a client-side only mod, so the server does not need it, and it works in single-player and on multiplayer servers where it only accesses files the user explicitly selects in a command argument. When playing single-player, Blocky File writes blocks straight into the world data, but on other setups it places them with setblock and loads them into the client world. Files can be shared with friends, but the author advises against sharing files that contain sensitive personal information. Blocky File is open source under the MIT License and runs on Fabric, Forge and NeoForge for 1.21.4 – 1.21.11, with Fabric covering the full range and the Forge and NeoForge builds starting at 1.21.6.
Key features
Block file storage
Blocks from the world are written to files and can be read back into a world later.
Block palette import and export
Palettes move through the clipboard, a file or the blocks of the world in either direction.
Configurable block palette map
A map file controls which block bits are used, so the palette can be adapted to the blocks in use.
In-game configuration screen
With Cloth Config API installed, settings can be changed in a GUI, and the configuration file can be reloaded.

How it compares
VoxExporter is server-side only, runs on Fabric 1.21.1 and is not open source under All rights reserved, so it is the opposite choice for server owners. Textbook is a client-side mod that is open source under the Mozilla Public License 2.0 with Fabric, Forge and Quilt files for 1.15 – 1.21.1. Export Stats is open source under the Apache License 2.0 and covers Fabric, Forge and NeoForge for 1.20 – 26.2, which reaches further than Blocky File.
