Where Are Quantum Break Save Files Located?
Quantum Break saves time-amok progress per user ID under a QuantumBreak folder in Local AppData on Windows.
Last updated
Quantum Break keeps saves in Local AppData under QuantumBreak, then a user-ID folder, then savegames with slot folders. A config preferences file beside them completes the set.
Cross-store moves need both halves: slot folder plus matching config. Steam Cloud and Xbox Cloud each mirror their own side, so pause sync while transplanting to stop reverts. Timeline choices ride inside the slots themselves.
Where Quantum Break stores this, by platform
%LOCALAPPDATA%\QuantumBreak
Per-ID savegames slots plus config preferences. Copy both halves with the game closed; Cloud paused during cross-store moves.
~/.local/share/Steam/steamapps/compatdata/474960/pfx/drive_c/users/steamuser/AppData/Local/QuantumBreak
Proton prefix for app ID 474960; the QuantumBreak tail inside mirrors Windows. Same two-halves rule for slot transfers.
Frequently asked questions
How do I back up Quantum Break saves?
Copy the whole QuantumBreak folder with the game closed. Per-ID subfolders keep profiles separate, so preserve the tree exactly.
How do I move a Quantum Break save between Steam and Game Pass?
Move both the savegames slot folder and the matching config preferences file together. One without the other loads incompletely or not at all.
