Where Are Somerville Save Files Located?
Where Somerville keeps saves on PC, and why the folder name is a number instead of your character name.
Last updated
Somerville keeps saves in its LocalLow company folder with a twist. Each profile sits in a subfolder named after the numeric Steam ID rather than a slot name. One machine with two Steam logins shows two numbered siblings.
The Microsoft Store build uses a separate container path and never touches this tree. Steam Cloud syncs the LocalLow folder, so pause it before manual restores. Copy the parent folder rather than single files to keep every profile intact. Checkpoints fill those folders on their own, so there are no manual slots to name.
Where Somerville stores this, by platform
%USERPROFILE%\AppData\LocalLow\Jumpship\Somerville
Holds one numbered subfolder per Steam64 account ID with progress inside. Back up the whole Somerville parent. Store builds instead use a Packages container.
Frequently asked questions
Why is my Somerville save folder just numbers?
That number is your 64 bit Steam ID, and the game files one subfolder per account. Back up the whole Somerville parent so every ID travels. Restoring means dropping the same numbered folder back with Cloud paused.
Can I move a Somerville Steam save to Game Pass?
No. The Store build keeps progress in a UWP container under its Packages folder, which is opaque and tied to the Xbox identity. Steam and Store saves do not mix, so pick one platform per playthrough.
