// 01 Why
Why Hollow Knight mod setups drift apart
Hollow Knight mods run on the community Modding API and live in the Mods folder deep inside the game's data folder. Most people install them with a mod installer like Lumafly or Scarab, one PC at a time, and a mod often needs a couple of library mods to work.
That's fine for one PC. For a randomizer race, a friend group playing together with HKMP, or a second PC of your own, everyone needs the same mods and versions, and matching them by hand means comparing lists.
SyncCrate syncs the Mods folder from one PC to the others. Files are compared by content, only the differences are copied, and you see the list before anything changes.

// 03 How it works
Sync Hollow Knight in three steps
Install and add the game
Install SyncCrate on every PC and add Hollow Knight in the Game Browser. Its folder is found automatically.
One PC hosts
The PC with the setup everyone should have clicks Start Hosting. The others pick it under Scan for Hosts on the same network, or paste its join code from anywhere.
Compare and sync
Check the list of new, changed and conflicting files, then Sync Now. Only the files that differ are copied, PC to PC.
TipEvery PC needs the Modding API installed once, with the same game version. SyncCrate copies the mods, not the API, and warns you if the game is still running.
// 04 Common problems
When Hollow Knight mods don't match
Different mods for a race or a group
Randomizer races and multiplayer sessions go wrong when one player has another version of a mod or is missing a library.
Everyone syncs the host's Mods folder, so every PC has the same files.
Mods on a second PC
Reinstalling each mod on another PC, with the right library mods, is slow and easy to get slightly wrong.
Sync the Mods folder from your main PC and it matches file for file.
A mod update for one player only
One person updating a mod is enough for the group to drift apart again.
The host updates once. Everyone else syncs and gets only the changed files.
Mods run code
Hollow Knight mods are
.dllfiles that run in the game..dllfiles are flagged before they sync, and nothing changes until you approve the list. Only sync with people you trust.

Good to know
- The Modding API isn't synced. It replaces game files in
Managed, which SyncCrate leaves alone. Install it on each PC, for example with your mod installer. - Saves aren't synced. Hollow Knight keeps them in your user profile, not in the game folder.
- Your mod installer may list synced mods as installed by hand until it rescans the folder.
- Steam or GOG doesn't matter: SyncCrate finds both, or point it at the game folder once.
// FAQ
Hollow Knight questions
Where do Hollow Knight mods go?
In hollow_knight_Data/Managed/Mods inside the game folder, once the Modding API is installed. SyncCrate finds Steam and GOG installs.
Does my friend need the Modding API installed?
Yes. The mods only load with the Modding API, and SyncCrate doesn't copy it. Install it on each PC with a mod installer, then sync the mods.
Can I use it to set up HKMP with friends?
Yes. Install the Modding API on every PC, the host sets up HKMP and any add-ons in their Mods folder, and everyone syncs. That way every player has the same versions.
Does SyncCrate sync my Hollow Knight saves?
No, only the Mods folder. Saves stay on each PC.
