What it does

The mod is a client-side tool that redirects singleplayer world storage to directories the player picks. It needs UniMixins as a required dependency, and Fabric API, Legacy Fabric API or SearchWorldEnhance can be added as optional companions. Builds cover b1.7.3 – 1.21.5 across Fabric, Forge, NeoForge, Babric and Legacy Fabric, and the code is open source under the GNU Lesser General Public License v3.0 or later.

Key features

  1. Custom save locations

    Singleplayer worlds can be read from and written to a directory other than the default saves folder.

  2. Client-only operation

    Only the player's client runs the mod, so multiplayer servers do not need it installed.

  3. Optional companions

    Fabric API, Legacy Fabric API and SearchWorldEnhance can be added alongside the mod when a setup calls for them.
