Valheim stores its save files at %USERPROFILE%\AppData\LocalLow\IronGate\Valheim\worlds_local on Windows. Checkpoint64 already knows this folder — it backs it up automatically and keeps earlier versions, so a corrupted or overwritten save is one click from restored.
Good to know: Make sure you make character and server are locally stored.
Where Valheim saves are stored
- Windows —
%USERPROFILE%\AppData\LocalLow\IronGate\Valheim\worlds_local
orC:\Program Files (x86)\Steam\userdata\<your Steam ID>\892970\remote\worlds
orC:\Program Files (x86)\Steam\userdata\<your Steam ID>\892970\remote\characters
or%USERPROFILE%\AppData\LocalLow\IronGate\Valheim - macOS —
~/Library/Application Support/IronGate/Valheim/worlds_local
or~/Library/Application Support/IronGate/Valheim - Linux —
~/.config/unity3d/IronGate/Valheim/worlds_local
or~/.config/unity3d/IronGate/Valheim
Where two locations are listed, which one is in use depends on the install (Checkpoint64 checks them in order and uses the first that exists).
Not sure where yours is? The Steam Save File Location guide explains how that path is built.
How to open the save folder
- Windows — press Win+R, paste
%USERPROFILE%\AppData\LocalLow\IronGate\Valheim\worlds_local, and press Enter (the AppData folder is hidden in Explorer, which is why this path is so easy to miss — pasting it skips the hunt). - macOS — in Finder press Cmd+Shift+G (Go to Folder) and paste
~/Library/Application Support/IronGate/Valheim/worlds_local.
Backing up Valheim saves automatically
- Install Checkpoint64 (free) and pick Valheim — the save path above is already preset.
- Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
- Restore any version in one click if a save corrupts, gets overwritten, or a mod breaks it.

Launch options: Checkpoint64 can start Valheim with 3 launch options you tick — see what each one does.
Sharing Valheim saves with friends
Valheim has co-op, so the folder above usually lives on one person's PC — whoever hosts. When they're offline nobody else can carry on, and if two people play separately, one session quietly overwrites the other.
Checkpoint64 lets a small group pass one Valheim world around instead of renting a dedicated server. Whoever plays next takes a server-enforced lock, pulls the latest save, plays, and pushes it back; everyone else stays read-only until the lock frees up, so nobody saves over anybody. Recent versions are kept, so a bad session is one restore away. The dedicated server alternative guide walks through the full take-turns flow.
