Where Are Scrap Mechanic Save Files Located?
Scrap Mechanic keeps Survival worlds, Custom builds and Blueprints per Steam user under Axolot Games AppData.
Last updated
Scrap Mechanic namespaces saves by Steam user. Survival and Creative worlds sit as .db files under Save, while workshop style creations sit under Blueprints. Keybinds and menu blueprints sit beside them. Each account gets its own User folder, so a second login on the same PC starts empty. Log into the right account before hunting missing builds.
The path includes your 64 bit SteamID, so guides show a placeholder where your number goes. Paste %APPDATA% to jump there fast. Steam Cloud covers part of it, but local backup is the reliable move before modding. Copy the whole User folder with Steam closed. Worlds sit as single database files beside Blueprint creations, and the numeric ID must match the target account.
