Godlike.Host offers hosted Satisfactory servers with its own game panel, SFTP access and free DDoS protection, if you would rather not host it yourself.
For most administrators, the safest way to move a Satisfactory save is the built-in Server Manager. Add or select the server, open Manage Saves, choose Upload Save, select the local .sav file, and then choose Load to make that upload the active save. To retrieve a server copy, use Manage Saves and choose Download.
There are two alternatives when the interface is not practical: upload the file through a hosting panel after stopping the server, or automate the transfer through the HTTPS API with administrator authentication. The correct method depends on whether you need a one-time move, direct filesystem access, or repeatable tooling.

What is the quickest supported way to upload a Satisfactory save?
Use Server Manager. This route keeps the save in the server’s own save-management system and separates transferring a file from activating it, which prevents an upload from becoming the live game accidentally.
- Open the Satisfactory Server Manager and add the dedicated server, or select it if it is already configured.
- Open the server’s Manage Saves tab.
- Choose Upload Save.
- Browse to the local
.savfile and submit the upload. - After the file appears in the server’s save list, select it and choose Load.
The final Load action matters. Uploading copies the file to the server; loading tells the dedicated server to use that save. If you only upload and do not load, the new file can remain available without replacing the currently active world.

You need administrator access to manage saves. If the upload is rejected, keep the original local file, note the exact error, and work through the compatibility and file-integrity checks later in this guide before trying to overwrite anything.

Make a backup before every replacement or load operation. Save files are stateful world data, so a mistake made during a version change, platform move, or cloud-synchronization event can remove the easiest path back to the previous world.
Keep an untouched local copy
Copy the original .sav file to a separate folder before uploading it. Do not use the only copy as the upload source if you can avoid it. Give backup copies a descriptive name that includes the world name and date, but retain the real .sav extension when you are ready to upload.
Check the server and client builds
The server validates save contents. A file can fail because its encoding is invalid or corrupted, because it is too old or too new for the server build, because the server cannot write it, or because the server cannot load it after writing. Confirm that the game and dedicated-server versions are compatible before transferring a large or important world.
Plan for cloud-sync conflicts
Switching versions, platforms, or machines can create cloud-sync conflicts. Keep a manual backup and decide which copy is authoritative before opening the game on another device. If a sync prompt appears, do not assume the newest timestamp is the correct world; compare the files and preserve both until you have confirmed which one contains the intended progress.
Recommended Free Tools
Confirm you have the right kind of file
Client saves use the .sav extension. A screenshot, archive, shortcut, or folder is not a substitute for the actual save file. If a file was compressed for transfer, extract it first and select the individual .sav file in Server Manager.
How do I upload a local save through Server Manager?
Server Manager is the normal one-off workflow. It is appropriate when you have administrator access but do not need to script the transfer or browse the server’s filesystem.
Step 1: Open the server entry
Start Server Manager and select the dedicated server that should receive the world. If the server is not listed, add it using the manager’s normal server-connection process before attempting save management.

Step 2: Open Manage Saves
Choose Manage Saves. This page is the supported interface for listing server saves and transferring files. Do not confuse it with a local game’s load menu: the manager is connected to the dedicated server and works with the server’s save directory.
Step 3: Choose Upload Save
Select Upload Save, browse to the backup or current local save, and confirm the file selection. Select the file with its original .sav extension. If your operating system hides extensions, enable extension display first so you do not accidentally upload a file such as world.sav.zip or world.sav.txt.
Step 4: Wait for the transfer to finish
Leave the manager open until it reports completion. A completed transfer means the server received the file; it does not by itself prove that the save is compatible or that it is now active.
Step 5: Load the uploaded save
Find the uploaded entry in the save list and choose Load. Loading activates that file on the dedicated server. If the server reports a validation, write, or load error, do not delete your local backup; use the error category to choose the next troubleshooting step.
How do I download a save from a Satisfactory server?
Use the same Manage Saves page, but choose Download for the server save you want to keep locally.
- Open Server Manager and select the correct server.
- Go to Manage Saves.
- Select the named save in the server list.
- Choose Download and select a safe local destination when prompted.
- Preserve the downloaded file as a backup before opening or modifying it.
The download is a copy operation. Keep the downloaded file separate from your existing client saves until you have confirmed that it is the intended world and that your client build can read it. If you plan to return it to the server later, retain the .sav extension and avoid renaming it in a way that hides which world it represents.
For scripted downloads, the API’s DownloadSaveGame operation returns the save itself as a file attachment when the requested named save exists. A nonexistent name produces a file-not-found error, so automation should treat that response as a lookup failure rather than as an empty save.
Where are Satisfactory saves stored?
Client saves and dedicated-server saves are different. A file in your personal client folder is not automatically in the server’s directory, and a server service may use a different Windows account from the account you use to play.

| Linux Steam Play client | Proton/compatdata save path | The exact directory depends on the Steam installation and is documented by the save-file guide; it is not the same as the native Windows path. |

Panel-based hosts generally expose the dedicated-server directory through a file manager or transfer tool. If you use that route, verify the panel’s mapped path instead of assuming it matches your personal client path.

When should I use a hosting-panel file manager?
A hosting panel is useful when the provider exposes the server filesystem and Server Manager is unavailable or inconvenient. The trade-off is a maintenance window: the documented workflow stops the server before replacing a file and starts it again afterward.
- Stop the Satisfactory dedicated server from the hosting panel.
- Open the panel’s file manager or transfer tool.
- Browse to the server’s
SaveGames/serverdirectory. - Upload the local
.savfile into that directory. - Start the dedicated server again.
- Open Server Manager, go to Manage Saves, select the uploaded save, and choose Load.
Stopping first reduces the chance that the running process will keep an old file open or save over the replacement during the transfer. Keep a copy of the previous server save before replacing it, particularly when the panel offers delete-and-upload rather than an atomic replacement.
This method requires filesystem or panel privileges in addition to game administration. If you cannot see the directory or cannot stop the process, use the Server Manager route or ask the host’s administrator to perform the transfer.
How does the HTTPS API upload and download work?
The API is the automation option. Most operations require authentication, and save upload and download require administrator privileges. It is appropriate for scheduled backups, migration scripts, or tools that must move several named saves without a manual interface.

The upload operation uses a multipart form-data request. One part named data contains the JSON request envelope, and another part named saveGameFile contains the binary save attachment. The request data includes these fields:
SaveNameidentifies the save name used by the server.LoadSaveGamecontrols whether the server loads the uploaded file immediately.EnableAdvancedGameSettingscarries the advanced-settings option expected by the API request.
The endpoint pattern is /api/v1/?function=UploadSaveGame. Send bearer authorization with an administrator token and construct the multipart body exactly as required by the API implementation. Do not send the .sav bytes as a JSON string; they belong in the saveGameFile attachment part.
Immediate loading and temporary API downtime
If LoadSaveGame is true, the dedicated server loads the new file as part of the upload. The API becomes temporarily unavailable while that load is processed. Automation should therefore allow for a short reconnect period instead of treating an immediate connection failure as proof that the upload failed.

Download request format
The download operation uses the endpoint pattern /api/v1/?function=DownloadSaveGame and takes a SaveName. On success, the response is the save file itself as an attachment. If that named save does not exist, the API returns a file-not-found error, which should be logged with the requested name.
Safer automation sequence
- Authenticate with an administrator bearer token.
- Confirm the source file exists locally and has the
.savextension. - Send the multipart upload with
SaveName,LoadSaveGame, andEnableAdvancedGameSettings. - Record the HTTP response and server error text before attempting a retry.
- If immediate loading was requested, wait for the API to become reachable again.
- For downloads, save the attachment without changing its contents and verify that the requested name was found.
Because the API can alter the active world, protect the token like any other administrator credential and restrict scripts to the minimum servers and directories they need.
Which transfer method fits my situation?
The three methods move the same kind of .sav data but differ in access, downtime, and automation.
| Method | Best for | Access required | Downtime or interruption | Main trade-off |
|---|---|---|---|---|
| Server Manager | Most administrators and one-time moves | Server administration access | No separate panel stop/start is specified for the UI workflow | Easiest supported interface, but manual |
| Hosting-panel files | Hosts exposing a file manager or direct transfer | Panel/filesystem access plus server controls | Stop the server, transfer the file, then start it and load the save | Direct and useful when the manager cannot upload, but requires a maintenance window |
| HTTPS API | Scripts, scheduled backups, and repeatable migrations | Administrator authentication and an API client | Loading an upload temporarily makes the API unavailable | Powerful and repeatable, but multipart request construction and error handling are your responsibility |
Choose Server Manager unless you have a specific reason to use another route. Choose a panel when you control the host’s files and can schedule a stop/start. Choose the API when repeatability or integration matters more than setup simplicity.
Do these 3 things before closing this tab:
1Scan for outdated or missing drivers - takes under a minute2Repair Windows errors before they cause bigger problems3Fix the driver behind crashes, sound loss and screen glitchesWhat errors stop a save from uploading or loading?
Most failures fall into a small set of categories. Identify the category before retrying so that a second attempt does not overwrite useful evidence or a working backup.
The file is rejected as invalid or corrupted
Confirm that the selected item is the real binary .sav file, not an archive or renamed document. Re-copy it from the untouched backup and retry. If the same file fails repeatedly, treat the local copy as damaged and find another known-good save rather than repeatedly uploading it.
The save is too old or too new
A version mismatch can prevent validation or loading. Confirm the dedicated server and the client that created the save are on compatible builds. If the server was recently updated or rolled back, use a save made for that compatible version instead of forcing the transfer.
The server cannot write the file
A write failure points to the destination rather than the save contents. Check that the server process has permission to write its SaveGames/server directory and that the panel or service account is using the expected profile. Through a panel, confirm that you uploaded into the mapped server directory, not a similarly named client directory.

The file uploads but will not load
Uploading and loading are separate operations, so a successful transfer does not guarantee activation. Verify the save name, confirm compatibility, and choose Load from the server’s save list. Preserve the previous active save until the new file has loaded successfully.
The API reports file not found
For DownloadSaveGame, file-not-found means the requested SaveName does not exist on that server. Check spelling, capitalization, and which server the token targets. Do not interpret the error as a zero-byte or empty save.
The API stops responding after an upload
If the upload requested LoadSaveGame=true, temporary API unavailability is expected while the server processes the load. Wait for the service to return before retrying; an immediate second upload can create confusion about which operation is active.
Are dedicated servers available on every Satisfactory platform?
The dedicated-server documentation covers desktop releases with Windows and Linux server binaries. It states that console releases do not have dedicated-server support. A console save therefore cannot be treated as a normal dedicated-server save through the workflows described here.

A save that exists on disk is not automatically portable across every release, and the server’s validation checks can reject a file that does not match its version expectations.
What is a safe repeatable backup routine?
Use a short checklist each time you move a world so that a routine transfer does not become an accidental replacement.
- Make a dated copy of the source
.savbefore opening the transfer tool. - Record whether the source is a client save or a dedicated-server save.
- Confirm the destination server’s operating system, service account, and game build.
- Use Manage Saves → Upload Save for the normal UI workflow.
- After uploading, select the entry and choose Load only when you intend to activate it.
- For panel transfers, stop the server first, place the file in
SaveGames/server, restart, and then load it in Server Manager. - For API transfers, use administrator bearer authentication, send the multipart fields correctly, and log the response.
- Keep the previous server save until the new world has loaded and the server is reachable.
- Store at least one backup outside the server directory so a failed write or replacement cannot remove every copy.
Frequently Asked Questions
Do I need to upload a folder or an individual save file?
Upload the individual client save with the .sav extension. The server’s save-management workflow operates on save files; a folder or compressed archive must be unpacked before you select the file.
Why can a save appear on the server but not be active?
Transfer and activation are separate actions. An uploaded entry remains available in the save list until an administrator selects it and chooses Load, so seeing the filename does not prove that players are connected to that world.
Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Repair Windows errors before they cause bigger problems3Scan for outdated or missing drivers - takes under a minuteWhat account owns the Linux server save directory?
The Linux path begins with ~, which expands to the home directory of the account running the dedicated-server process. If you inspect another user’s home directory, you may conclude incorrectly that the server has no saves.
Can a regular player use the save API?
Save upload and download API operations require administrator authentication. A player without those privileges must ask a server administrator to perform the transfer or provide a copy through the approved server-management workflow.
