Here's exactly where Dyson Sphere Program keeps your galaxy saves on PC, how to open the folder, and how to back up a .dsv file before a big factory experiment.
Save file locations
%USERPROFILE%\Documents\Dyson Sphere Program\Save
Full path: C:\Users\<YourName>\Documents\Dyson Sphere Program\Save . Saves are .dsv files; you'll also see _lastexit and _autosave files you can fall back on.
Cloud saves
Dyson Sphere Program uses Steam Cloud, so saves usually follow your Steam account to another PC. The .dsv files in Documents are the local copy — copy them out manually if Cloud is off, or to keep a snapshot of a huge factory before you tear it apart.
How to open the save folder
- Press Win + R to open the Run box.
- Paste %USERPROFILE%\Documents\Dyson Sphere Program\Save and press Enter.
- Copy the .dsv file (and its auto-save) for the galaxy you want to keep.
- Back up before major mod changes or a risky build.
Save problems & fixes
My DSP save won't load or is corrupted
In %USERPROFILE%\Documents\Dyson Sphere Program\Save, load the matching _lastexit or _autosave file instead of the broken .dsv, or restore your manual backup.
Steam Cloud restored an old galaxy
Exit the game, replace the .dsv in the Save folder with your manual backup, then relaunch — or disable Steam Cloud for the title first so it doesn't re-sync the old file.
FAQ
Where is the Dyson Sphere Program save on PC?
C:\Users\<YourName>\Documents\Dyson Sphere Program\Save — each galaxy is a .dsv file.
What are the _autosave and _lastexit files?
They're automatic fallbacks the game writes alongside your manual .dsv saves. If a manual save breaks, load the _lastexit or _autosave copy.
Does Dyson Sphere Program use Steam Cloud?
Yes — saves sync via Steam Cloud, but keep a local copy of the .dsv file in case a sync conflict overwrites your latest galaxy.
