Game Hub / Save Reference

NieR: Automata Save Files & Tools

NieR: Automata PC save location, backup, file-format, launcher, cloud-sync, and compatibility reference. This Game Hub documents save-file facts without implying that a game-specific Save Editor is available.

01 / Overview

Save reference at a glance.

Game Hubs separate documented save-file facts from actual Tool support. A Game Hub can be useful even when no custom editor exists.

NieR: Automata is a case where backing up only “the save slot” can miss important surrounding state. Steam exposes three SlotData files but also stores GameData and SystemData in the same Documents directory. Ending and presentation state can therefore outlive a single slot replacement. SaveEditor recommends treating the folder as one backup set, then making any slot-level experiment only on a copy. Microsoft Store is additionally separated by its WGS container, so its files should not be treated as Steam .dat files solely because the gameplay is the same.

For this PC reference, the documented storage is Windows: Steam: %USERPROFILE%DocumentsMy GamesNieR_Automata ; Microsoft Store: %LOCALAPPDATA%Packages39EA002F.NieRAutomataPC_n746a19ndrrjgSystemAppDatawgs. The known file or folder pattern is Steam: SlotData_0.dat, SlotData_1.dat, SlotData_2.dat plus GameData.dat and SystemData.dat.. Steam stores three slot files alongside broader game/system data. Microsoft Store wraps saves in WGS containers. A slot file alone does not necessarily represent every piece of progression or presentation state.

Backup guidance: Back up the complete NieR_Automata folder on Steam, including SlotData, GameData, and SystemData, before replacing one slot. Preserve the full WGS tree on Microsoft Store. Steam Cloud and Xbox Cloud can restore saves for their storefronts. Launcher and cloud context matters because Steam and Microsoft Store use different containers; cross-store transfers may require renaming and account/ID-aware handling rather than a raw overwrite.

Compatibility and recovery should stay conservative. Ending-related and global progression can involve GameData in addition to SlotData. Do not assume one slot file is the only state worth preserving. If the expected progress is not visible, If a slot vanishes or fails to load, verify the exact SlotData index, Steam account, cloud-conflict choice, and whether broader GameData/SystemData came from the same backup set. SaveEditor.com only labels a game-specific editor as available when a separate linked Tool has a verified operational runtime; this reference page by itself is not an editor claim.

Compatibility note

Ending-related and global progression can involve GameData in addition to SlotData. Do not assume one slot file is the only state worth preserving.

02 / Save locations

Where the save files are stored.

Paths are displayed only when they have been explicitly documented for this Game Hub. Environment variables and launcher-specific differences should remain visible instead of being silently normalized.

05 / Backup

Protect the original before editing.

Save editing should be reversible. Keep an untouched copy outside the active save directory before replacing, converting, repairing, or modifying a save.

  1. 01
    Close the game.

    Avoid modifying a save while the game or launcher may still be writing to it.

  2. 02
    Copy the entire relevant save set.

    Some games use multiple files, profile folders, metadata, or companion files rather than one isolated save.

  3. 03
    Store the backup elsewhere.

    Use a separate folder or archive so cloud sync or the game cannot overwrite the untouched backup.

  4. 04
    Edit a copy, then validate.

    Follow the exact compatibility and processing notes on the Tool page before replacing the active save.

Game-specific backup note

Back up the complete NieR_Automata folder on Steam, including SlotData, GameData, and SystemData, before replacing one slot. Preserve the full WGS tree on Microsoft Store.

06 / Troubleshooting

When a save is missing or rejected.

Start with reversible checks. Do not delete or overwrite the only copy while diagnosing a path, cloud-sync, version, or format problem.

Game-specific notes

If a slot vanishes or fails to load, verify the exact SlotData index, Steam account, cloud-conflict choice, and whether broader GameData/SystemData came from the same backup set.

A

Confirm the correct profile.

Games, launchers, and operating systems may keep separate save folders for different users, editions, or profiles.

B

Check cloud synchronization.

A cloud service can restore an older file or overwrite a local change. Preserve both copies before resolving a conflict.

C

Check Tool compatibility.

A matching filename does not prove a matching format. Verify platform, game version, extension, and Tool support state.

D

Restore the untouched backup.

If the game rejects a modified save, return to the original backup before attempting another change.
