Control is a storefront-sensitive case: first identify Steam, Epic, or GOG, then copy that entire save root. Do not flatten the three layouts into one generic path during migration.
For this PC reference, the documented storage is Windows: Steam: <Steam-folder>userdata<account-id>870780remote ; Epic: %LOCALAPPDATA%RemedyControlDefault-Epic-User ; GOG: %USERPROFILE%DocumentsMy GamesControlSaves. The known file or folder pattern is storefront-specific Control slot/chunk records. Control uses different save roots across Steam, Epic, and GOG. A save-set is not identified safely until the storefront directory is known, and recent GOG/Epic variants can use different Default-* profile folder names.
Backup guidance: Close Control Ultimate Edition, let the launcher finish any synchronization, then copy the complete documented save directory to a dated folder outside the live path. Preserve companion files rather than selecting only the newest-looking record. Steam, Epic, and GOG can each synchronize their own save root. GOG documents local backup/restore separately from Galaxy Cloud Saves. Launcher and cloud context matters because The active Steam, Epic Games Store, GOG Galaxy installation determines which local profile and cloud copy can overwrite the save. Identify the storefront and account before restoring files.
Compatibility and recovery should stay conservative. Treat saves as version-, storefront-, account-, and mod-sensitive unless the game or a separately verified migration workflow proves otherwise. A similar filename or extension is not evidence that two releases are interchangeable. If the expected progress is not visible, If progress is missing after a restore, confirm the active Windows account, storefront/profile, cloud state, and exact directory first. Restore the untouched backup before experimenting with individual files or older autosaves.
