PEAK Save File Location: How to Find, Backup, and Transfer Your Progress (Steam & AppData)

If you have spent hours stumbling up cliffs, reviving your friends at the worst possible moment, and somehow surviving a run that looked doomed from the first few minutes, losing your PEAK progress is probably the last thing you want to deal with.

The problem is that PEAK does not behave like a typical single-player game with an obvious savegame.sav sitting in the installation folder. That makes the whole subject of PEAK save files surprisingly confusing. You can open the game’s directory, search through AppData, check Steam userdata, and still wonder where your actual progress went.

I ran into the same confusion when looking into the game’s file structure. The important thing to understand is that local PEAK files are not necessarily the same thing as your long-term progression. Some files are useful for configuration and troubleshooting, while other parts of your player state are tied much more closely to Steam and the game’s online systems.

So, if you’re trying to back up PEAK, move to another PC, troubleshoot corrupted files, or simply understand where the game keeps its data, here’s the practical version.

Where Is the PEAK Save File Located on Windows?

For the standard Steam PC installation, the most useful local directory to check is:

C:\Users\[Your Username]\AppData\LocalLow\LandCrab\PEAK

This is the directory associated with PEAK’s Unity-generated local data.

However, there is an important distinction here: don’t assume everything inside this folder is your complete player save. If you’re expecting a huge file containing every unlocked item, badge, run, and achievement, you may be disappointed.

The folder is particularly useful for logs, local configuration information, and troubleshooting files.

One file you may encounter is:

Player.log

This log can be extremely helpful if PEAK crashes, refuses to launch correctly, or behaves strangely. If you’re contacting support, having the relevant log available can also save you a lot of back-and-forth.

Quick PEAK Local Folder Path

The big takeaway is simple: the LocalLow folder is worth backing up, but it shouldn’t automatically be treated as a complete replacement for Steam’s cloud/account data.

How to Open the Hidden AppData Folder

Windows hides AppData by default, which is why this directory can feel like it’s not even there.

The fastest way to reach it is through the Run dialog.

Method 1: Use Windows Run

1. Press Windows + R.
2. Enter %appdata%.
3. Press Enter.
4. Windows will open the Roaming folder.
5. Move up to the main AppData directory.
6. Open LocalLow.
7. Go to LandCrab > PEAK.

You can also skip the navigation entirely by entering this path into File Explorer:

%USERPROFILE%\AppData\LocalLow\LandCrab\PEAK

That’s the method I’d recommend. It’s faster and avoids clicking through several hidden folders.

Method 2: Show Hidden Files

If you’d rather browse manually:

1. Open File Explorer.
2. Select View.
3. Enable Hidden items.
4. Open your Windows user folder.
5. Enter AppData.
6. Open LocalLow.
7. Navigate to LandCrab > PEAK.

Once you’ve enabled hidden files, you’ll also be able to see other application folders stored under your Windows profile.

Does PEAK Have a Traditional Save File?

This is where things get interesting.

If you’re coming from a traditional offline game, you might expect something like:

Save01.sav

or

PlayerData.dat

You shouldn’t necessarily expect PEAK to work that way.

PEAK is built around multiplayer gameplay, Steam integration, achievements, unlocks, and temporary run progression, so its data structure doesn’t feel like that of a conventional offline adventure game.

Some local information exists, but your entire progression isn’t simply represented by one convenient save file that you can copy between computers.

That’s why randomly copying the game’s installation folder usually isn’t a reliable way to migrate everything.

What About Cosmetics and Unlocks?

This is another area where players can easily get confused.

Your cosmetics, badges, achievements, and other progression-related elements can be connected to Steam and the game’s online systems rather than existing as an easily editable local save document.

In practical terms, that means your Steam account is far more important than the PEAK installation directory when it comes to recovering account-associated progress.

If you reinstall Windows and then install PEAK again through the same Steam account, you shouldn’t automatically assume that losing the LocalLow folder means you’ve lost every unlock forever.

PEAK Steam Cloud: The First Thing I Would Check

Before deleting anything, I would always check Steam Cloud.

Open your Steam Library and find PEAK.

Then:

1. Right-click PEAK.
2. Select Properties.
3. Open the General section.
4. Look for Steam Cloud synchronization.
5. Make sure synchronization is enabled.

I’d also give Steam a moment to finish syncing before shutting down the client.

This is especially important if you’re moving between two computers. You don’t want to make a local backup while Steam is still deciding which version of your data is current.

How to Verify PEAK’s Game Files

If you’re having crashes, missing local files, or strange behavior, Steam’s file verification tool is another easy first step.

Go to:

PEAK → Properties → Installed Files → Verify integrity of game files

Steam will compare the installed game files against its expected version and replace damaged or missing files where necessary.

Keep in mind, though, that file verification isn’t a magic save-recovery tool. It repairs the game installation. It doesn’t recreate a missing personal progression state that was never stored in the installation directory.

That’s an important distinction.

Where Is PEAK’s Steam Userdata Folder?

There is another directory worth knowing about if you’re doing deeper troubleshooting:

C:\Program Files (x86)\Steam\userdata\[Your SteamID3]\3527290\

The 3527290 folder corresponds to PEAK’s Steam application ID.

Depending on your Steam installation location and configuration, your actual Steam directory may be somewhere else, so don’t blindly assume it will always be under C:\Program Files (x86).

This userdata directory can contain Steam-related local information and cloud synchronization data.

For a serious backup, I personally prefer keeping both the LocalLow PEAK folder and the relevant Steam userdata folder rather than betting everything on one directory.

PEAK Save Location on Steam Deck

Steam Deck users have another layer of complexity because the Windows version of PEAK runs through Proton.

Instead of seeing a normal Windows C:\Users structure, the game gets a virtual Windows environment inside the Proton compatibility prefix.

A commonly used path is:

/home/deck/.steam/steam/steamapps/compatdata/3527290/pfx/drive_c/users/steamuser/AppData/LocalLow/LandCrab/PEAK/

The important number here is again:

3527290

That’s PEAK’s Steam AppID.

How to Find the Folder on Steam Deck

1. Switch the Steam Deck to Desktop Mode.
2. Open Dolphin.
3. Enable Show Hidden Files.
4. Open .steam.
5. Go to steam > steamapps > compatdata.
6. Find 3527290.
7. Open pfx.
8. Follow drive_c > users > steamuser > AppData > LocalLow.
9. Open LandCrab > PEAK.

If you don’t see .steam, don’t worry. That’s simply a hidden directory.

Pressing Ctrl + H in Dolphin is a quick way to toggle hidden files.

Should You Back Up the PEAK Folder?

Yes, especially before making major changes.

Even if the LocalLow directory isn’t a traditional complete save file, backing it up costs almost nothing.

I’d recommend closing PEAK first, allowing Steam to finish synchronization, and then copying the relevant folder somewhere safe.

For example:

PEAK_Backup_August_2026

If you’re experimenting with mods, reinstalling the game, moving between operating systems, or troubleshooting corruption, having that folder available can make things much less stressful.

For important backups, I’d keep a copy on another drive rather than storing the only backup next to the original.

Can You Transfer a PEAK Save From One PC to Another?

This is where I would be careful.

If you’re moving from one Windows PC to another while using the same legitimate Steam account, Steam Cloud is the first thing I’d rely on.

A simple workflow is:

1. Install PEAK on the new PC.
2. Log into the same Steam account.
3. Confirm Steam Cloud is enabled.
4. Allow synchronization to finish.
5. Launch the game.
6. Check whether your expected progression and unlocks are present.

You can additionally copy your old LocalLow\LandCrab\PEAK folder if you’re trying to preserve local configuration or logs, but I wouldn’t treat that folder as a guaranteed full progression transfer.

What About Moving a Save From an Offline or Pirated Copy?

This is a much more complicated situation.

If you’ve previously played an unofficial or offline build and later purchased PEAK legitimately through Steam, there is no reason to expect that simply copying random folders will recreate your Steam-associated progression.

Achievements, account information, online progression, and other Steam-connected data aren’t equivalent to copying a normal offline .sav file.

So if you’re switching to the legitimate Steam release, the safest approach is to treat the Steam version as a fresh official profile and let it synchronize with your Steam account.

I wouldn’t recommend trying to force unrelated files into the Steam installation directory. At best, they may do nothing. At worst, they can create additional troubleshooting headaches.

What If My PEAK Progress or Cosmetics Are Missing?

Don’t immediately delete everything.

Start with the least destructive options.

1. Restart Steam

Completely exit Steam and start it again. Then allow PEAK to synchronize.

2. Check Steam Cloud

Make sure Cloud synchronization is enabled and hasn’t reported a conflict.

3. Verify Game Files

Use Steam’s Verify integrity of game files option.

4. Back Up Local Data

Before deleting or changing anything, copy:

AppData\LocalLow\LandCrab\PEAK

somewhere safe.

5. Rebuild Local Configuration

If the local configuration appears corrupted, you can rename the PEAK folder rather than immediately deleting it.

For example:

PEAK → PEAK_Backup

Then start the game again and allow it to create a fresh local directory.

This is much safer than deleting the original folder because you can restore files if the experiment doesn’t solve the problem.

What About Mods and Third-Party Save Managers?

This is where things become much less predictable.

Community-made tools, BepInEx plugins, custom save managers, and other modifications can introduce their own directories and file formats. If you’ve installed mods, don’t assume their data will be stored in the standard PEAK LocalLow folder.

Some tools may create their own backup directories or generate custom save files.

That’s why the best rule is:

If you’ve modified PEAK, check the documentation for the specific mod before deleting or replacing files.

Don’t blindly copy third-party files into a clean Steam installation and expect everything to work.

My Recommended PEAK Backup Routine

If you’re someone who has already lost game progress before, I’d keep the process extremely simple.

Before a major update, reinstall, Windows reset, or mod experiment:

1. Close PEAK.

2. Let Steam finish Cloud synchronization.

3. Copy the LocalLow PEAK directory.

4. Back up the relevant Steam userdata directory if you’re doing a full migration.

5. Give the backup a date-based name.

For example:

PEAK_Backup_2026-08-13

That way, if something goes wrong, you know exactly which backup you’re looking at.

Final Thoughts: Don’t Confuse Local Files With Your Whole PEAK Profile

PEAK is one of those games where the phrase “save file location” is slightly misleading.

There is a real local directory, and it’s absolutely useful for logs, configuration, troubleshooting, and backups. But that doesn’t mean there’s one magical file containing your entire PEAK career.

That’s the biggest thing I would keep in mind.

If you’re playing on Steam, Steam Cloud and your Steam account are just as important as the local PEAK folder. If you’re on Steam Deck, the same data is tucked away inside Proton’s compatibility directory, which makes it look much more complicated than it actually is.

Personally, if I were preparing to reinstall Windows or move to another machine, I’d make a complete backup of the LocalLow\LandCrab\PEAK folder, preserve the relevant Steam userdata directory, and verify Steam Cloud before touching anything. It’s a few minutes of work, and it’s a lot better than discovering after a reinstall that you should have backed something up.

And if you’re only looking for Player.log because PEAK is crashing, you don’t need to go hunting through the entire Steam installation. Start with:

%USERPROFILE%\AppData\LocalLow\LandCrab\PEAK

That’s the folder I’d check first.
