CurseForge is one of the largest platforms for Minecraft mod packs, and its launcher makes installing and managing complex modded setups straightforward. But while CurseForge excels at getting everyone on the same mods, it does not solve the fundamental multiplayer problem: the world save lives on the host’s machine.

When you are deep into a mod pack like All The Mods, RLCraft, or Create Above and Beyond, the progress you make is substantial. Builds, automation setups, quest completions, explored dimensions - all of it locked behind one player’s availability. If the host cannot play, the modded world sits idle.

Where Does CurseForge Save Minecraft Worlds?

The CurseForge app keeps each modpack as a self-contained instance, and your worlds live inside that instance’s saves folder. The default location on Windows is:

C:\Users\<YourUsername>\curseforge\minecraft\Instances\<ModpackName>\saves\<WorldName>\

The fastest way to open it: in the CurseForge app go to Minecraft -> My Modpacks, click the … (three dots) next to the modpack’s Play button, choose Open Folder, then open the saves subfolder. Each world is its own folder containing level.dat, a region folder, and playerdata.

Two things worth knowing:

  • If you set a custom modding folder (App Settings -> Minecraft -> Minecraft Modding Folder), your instances live under <CustomFolder>\Instances\... instead.
  • This is different from vanilla (non-modpack) Minecraft, which saves to %APPDATA%\.minecraft\saves. Older Curse/Twitch launcher installs used Documents\Curse\Minecraft\Instances\....

Finding the folder is step one. The bigger co-op problem is that this world only exists on the host’s PC - so when they are offline, nobody else can load it. That is what SaveSync fixes.

How SaveSync Shares Your Modded World

SaveSync synchronizes your Minecraft world save across all players in your group. After each session, the latest save is pushed to everyone. Any player can load the world in their CurseForge instance and host for the group.

This means no dedicated server, no monthly fees, and no single point of failure.

How to Set Up SaveSync for Minecraft CurseForge

  1. Install SaveSync from Steam. All players need it installed.
  2. Create a sync group and add your friends.
  3. Find your CurseForge saves folder (the ...\curseforge\minecraft\Instances\<ModpackName>\saves\ path covered above - use … -> Open Folder in the app). Point SaveSync to the specific world folder you want to share.
  4. Play as usual. Host through “Open to LAN” or a locally run server within the mod pack.
  5. SaveSync syncs the save automatically when the session ends.
  6. Any player can host the next session. They load the world from their own synced copy.

Why Use SaveSync Instead of Server Hosting or Manual Transfers

Modded Minecraft adds extra complexity to every aspect of multiplayer. Here is how SaveSync compares to the alternatives:

  • Dedicated servers are expensive for modded packs. Mod-heavy instances need significant RAM - often 6GB or more. That translates to costly server plans. SaveSync eliminates the server entirely.
  • Server-side mod configuration is painful. Many mods behave differently on servers versus single-player, requiring extra config work. With SaveSync, everyone runs the world locally in single-player mode with LAN hosting, which is the simplest and most compatible setup.
  • Manual file sharing breaks with large saves. Modded Minecraft worlds can grow to hundreds of megabytes or more. Transferring that through Discord every session is impractical. SaveSync handles large files efficiently with incremental syncing.
  • CurseForge manages mods, not saves. The launcher keeps everyone on the same mod versions, which is great. But it has no mechanism for sharing the world save. SaveSync fills that gap.

Together, CurseForge and SaveSync cover both halves of the problem: mods stay in sync through CurseForge, and the world stays in sync through SaveSync.

Keep Your Modded Adventure Going

Whether you are building a Create contraption, exploring Twilight Forest, or automating with Applied Energistics, your progress should not depend on one player. SaveSync ensures everyone can access the world, so your modded Minecraft journey continues on everyone’s schedule.
