Where Are SULFUR Save Files Located?
SULFUR stores saves as Easy Save 3 files in LocalLow, while most settings live in the Windows registry.
Last updated
SULFUR is Perfect Random's old-school action-adventure, released on October 28, 2026 and built in Unity. Its saves land in %USERPROFILE%\AppData\LocalLow\Perfect Random\Sulfur as .es3 files, the format used by the Easy Save 3 asset.
Settings take a different route. Most of them sit in HKEY_CURRENT_USER\Software\Perfect Random\Sulfur, so a folder backup alone will not carry your options to a new PC. The save files are the part that matters for progress, and Steam Cloud is enabled for them. Back up the folder when you move machines; the registry key is optional.
Where SULFUR stores this, by platform
%USERPROFILE%\AppData\LocalLow\Perfect Random\Sulfur
Save files use the .es3 extension. The game can leave more than one save or backup file here, so copy the whole folder instead of picking a single file.
HKEY_CURRENT_USER\Software\Perfect Random\Sulfur
Player settings such as options and keybinds are stored as registry values here. Deleting the key resets settings but leaves save files alone.
Frequently asked questions
Where are SULFUR save files?
In %USERPROFILE%\AppData\LocalLow\Perfect Random\Sulfur. The files end in .es3. Copy the entire folder, since the game can keep more than one save or backup file there.
Where does SULFUR store settings?
Under HKEY_CURRENT_USER\Software\Perfect Random\Sulfur in the registry. These are options, not progress. Removing the key resets your settings the next time the game starts, and saves stay untouched.
Does SULFUR use Steam Cloud?
Yes, Steam Cloud is enabled. Even so, keep a manual copy of the LocalLow folder if a run matters to you, since cloud sync only helps while both machines are online and signed in.
