Where to Find Hearts of Iron IV Save Files
The save files are stored in your user documents folder under Paradox Interactive\Hearts of Iron IV\save games.
On Windows, the full path looks like Documents\Paradox Interactive\Hearts of Iron IV\save games\; on macOS it’s ~/Documents/Paradox Interactive/Hearts of Iron IV/save games/; and on Linux it’s ~/.local/share/Paradox Interactive/Hearts of Iron IV/save games/. These folders hold uncompressed .hoi4 files — each one is either an Ironman save or a regular one. Honestly, I find it handy to know that, unless you’ve turned on cloud saving, the game keeps everything right on your machine.
Step-by-Step: Accessing Your Save Files
You can access your save files by opening your file explorer and navigating to the OS‑specific save games folder.
For Windows, hit Win + E and browse to C:\Users\[YourUsername]\Documents\Paradox Interactive\Hearts of Iron IV\save games\. On macOS, launch Finder, press Cmd + Shift + G, then type ~/Documents/Paradox Interactive/Hearts of Iron IV/save games/. On Linux, fire up your file manager and paste ~/.local/share/Paradox Interactive/Hearts of Iron IV/save games/ into the location bar. You’ll see files with the .hoi4 extension — feel free to copy, delete, or tweak them as you like. If you’re planning to edit a save, just set save_as_binary=no in Documents\Paradox Interactive\Hearts of Iron IV\settings.txt (check out the Steam Support page for more on finding game files).
