Game Hub / Save Reference

Slay the Spire Save Files & Tools

Slay the Spire 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.

PC

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.

Slay the Spire is different from the usual one-folder save model: PCGamingWiki lists preferences, runs, saves, and betaPreferences as game data. That means “backup the save file” is incomplete advice. A user may restore card/progression information yet lose an active run or related preferences if only one directory is copied. SaveEditor therefore treats the four directories as one logical backup set for standard desktop builds while keeping the Microsoft Store package path separate.

For this PC reference, the documented storage is Windows: Desktop builds: <path-to-game>preferences, <path-to-game>runs, <path-to-game>saves and betaPreferences ; Microsoft Store: %LOCALAPPDATA%PackagesHumbleBundle.SlayTheSpire_q2mcdwmzx4qjaLocalCacheLocalMicrosoftWritablePackageRootsaves. The known file or folder pattern is Multiple files across preferences, runs, saves, and betaPreferences rather than one universal slot file.. Slay the Spire stores meaningful state in several sibling directories under the installation resources for standard desktop builds. Backing up only saves can omit preferences/unlocks or run state.

Backup guidance: Back up preferences, runs, saves, and betaPreferences together before reinstalling or moving the game. On Microsoft Store, preserve the package-local save path separately. Steam Cloud and Xbox Cloud support are documented depending on edition. Launcher and cloud context matters because The Microsoft Store sandbox path differs significantly from Steam/GOG. Standard desktop installs can keep data alongside game resources, so reinstall/move operations deserve an explicit backup first.

Compatibility and recovery should stay conservative. Unlock/progression data and an in-progress run are not necessarily represented by the same file. A partial directory copy can therefore restore one aspect but not another. If the expected progress is not visible, If ascension/unlocks or the current run do not match after restoration, compare all four data directories rather than repeatedly overwriting the saves folder alone. 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

Unlock/progression data and an in-progress run are not necessarily represented by the same file. A partial directory copy can therefore restore one aspect but not another.

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.

Launcher / edition differences

The Microsoft Store sandbox path differs significantly from Steam/GOG. Standard desktop installs can keep data alongside game resources, so reinstall/move operations deserve an explicit backup first.

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 preferences, runs, saves, and betaPreferences together before reinstalling or moving the game. On Microsoft Store, preserve the package-local save path separately.

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 ascension/unlocks or the current run do not match after restoration, compare all four data directories rather than repeatedly overwriting the saves folder alone.

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.
