Deltarune Save File Location (Windows, Mac, Linux, Steam Deck)

Windows save file location

On Windows, both the Steam and itch.io versions of Deltarune — the demo and the full release alike — save to the same folder: %LOCALAPPDATA%\DELTARUNE. That environment variable expands to C:\Users\<you>\AppData\Local\DELTARUNE, where <you> is your Windows username.

The only wrinkle is that AppData is a hidden folder, so clicking through File Explorer normally gets you nowhere. The fastest way in:

1. Press Win + R to open the Run dialog.
2. Type %LOCALAPPDATA%\DELTARUNE and press Enter. File Explorer jumps straight to the save folder, hidden folders and all.

Prefer to browse? Reveal hidden items first — in File Explorer, choose View → Show → Hidden items — then navigate to C:\Users\<you>\AppData\Local\DELTARUNE. You can also paste the %LOCALAPPDATA%\DELTARUNE shortcut directly into the Explorer address bar; it works the same way.

Inside you will find plain-text files named like filech2_0 — one value per line, no checksum — which is exactly why a browser-based save editor can read and rewrite them safely.

Mac save file location

On macOS, Deltarune saves live inside your user Library: ~/Library/Application Support/com.tobyfox.deltarune/. The Library folder is hidden too, so skip the clicking and use Finder's Go to Folder command:

1. Open Finder.
2. Choose Go → Go to Folder in the menu bar (or press ⇧ Shift + ⌘ Command + G).
3. Paste ~/Library/Application Support/com.tobyfox.deltarune/ and press Return.

As on Windows, the Steam and itch.io builds share this folder, and demo saves sit alongside full-release saves, so there is only one place to look.

Linux and Steam Deck save file location

On Linux — including a Steam Deck in desktop mode — Deltarune runs through Proton, so the save folder hides inside the Proton prefix rather than a native directory:

• Full release (appid 1671210): ~/.steam/steam/steamapps/compatdata/1671210/pfx/drive_c/users/steamuser/AppData/Local/DELTARUNE
• Chapter 1 & 2 demo (appid 1690940): ~/.steam/steam/steamapps/compatdata/1690940/pfx/drive_c/users/steamuser/AppData/Local/DELTARUNE

On a Steam Deck, ~ is /home/deck. Switch to desktop mode, open the Dolphin file manager, and enable Show Hidden Files from the menu, because the .steam folder starts with a dot and stays invisible otherwise.

The Steam Deck demo trap: on Windows and Mac, full-release Deltarune finds your demo progress automatically. On Linux and Steam Deck it does not, because the demo and the full game live in separate Proton prefixes that never see each other. If your Chapter 1 & 2 progress never showed up after upgrading, copy the whole DELTARUNE folder from the 1690940 prefix into the 1671210 prefix by hand, then launch the game.

Nintendo Switch and PlayStation: locked out of your saves

There is no Deltarune save file location you can browse to on Nintendo Switch, PS4, or PS5. Console saves sit inside system storage, and neither platform gives users file-level access to them.

On Switch, the only way to extract a save is custom firmware plus a homebrew save manager such as JKSV or Checkpoint — a setup that carries real risk for your console and your data, and one we are not going to walk you through here. The official options are limited to cloud backups through Nintendo Switch Online or PlayStation Plus, and the in-game import that carries demo progress into the full release.

That is why our save editor is PC, Mac, and Linux only: consoles simply never hand you a file to open. If your only copy of Deltarune is on a console, save editing is off the table without homebrew.

Deltarune save file names, decoded

Every file in the folder follows the pattern filechN_x: N is the chapter number (1-4), and the suffix says what the file is for. The naming has held from Chapter 1 through the Chapter 3 and 4 release in June 2025.

So a Chapter 2 save in the first slot is filech2_0, and a Chapter 3 save in the second slot is filech3_1. The files themselves are plain text with one value per line and no checksum: Chapter 1 saves run 10,318 lines, while Chapters 2, 3 and 4 share a newer 3,055-line format. Our editor detects the chapter from those line counts — and from the filename when chapters share a format — with a manual chapter switcher as backup. Editing a Chapter 3 file? The Chapter 3 save editor guide covers what is worth changing in Tenna's TV World.

Before you edit: back up the folder

Rule one of save editing: copy the entire DELTARUNE folder somewhere safe before you change anything. Paste it on your desktop, rename it DELTARUNE-backup, and you have a one-step undo for every possible mistake.

Steam Cloud can undo your edits. Steam may restore your old files from the cloud right over your edited ones. While swapping saves, open Steam → Library → Deltarune → Properties → General and temporarily uncheck Keep games saves in the Steam Cloud. Swap the files, launch the game once to confirm the edit stuck, then re-enable it.

And always close Deltarune completely before copying files in or out. If the game is running, it can overwrite your edited file the next time it saves — or load the old version and make your edit vanish.
