Andromeda follows the BioWare Documents convention but it is not part of Legendary Edition. Keep its Save directory isolated from older Mass Effect folders and label manual backups with the active EA/Steam account.
For this PC reference, the documented storage is Windows: %USERPROFILE%DocumentsBioWareMass Effect AndromedaSave. The known file or folder pattern is profile and slot records in the BioWare Save folder. Andromeda uses BioWare save records in a dedicated Documents profile. Preserve the directory as a set because profile metadata and individual saves can be related.
Backup guidance: Close Mass Effect: Andromeda, 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. EA cloud features can synchronize the same local profile even when launched through Steam. Launcher and cloud context matters because The active EA app, Steam 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.
