Where Are Blades of Fire Save Files Located?
Blades of Fire saves under AppData Local MercurySteam and Documents MercurySteam, each inside a per-user hex folder. Epic, Steam and GOG share the pattern.
Last updated
MercurySteam splits this game across two roots, which catches people out. There is a copy under AppData Local and another under Documents, both under MercurySteam then Blades of Fire, then a hex user ID folder. You need the ID folder from both sides for a full backup.
The pattern is the same on Epic, Steam and GOG. Only the cloud provider changes. The Documents copy is the fragile one, since OneDrive backup treats it as syncable user data. If you run OneDrive, verify which copy your install actually writes before assuming a backup worked.
Where Blades of Fire stores this, by platform
%LOCALAPPDATA%\MercurySteam\Blades of Fire\<user-id>
Config and saves live under a hex user ID folder here. The publisher documents this exact pattern. Copy the whole ID folder, not single files, with the game closed.
%USERPROFILE%\Documents\MercurySteam\Blades of Fire\<user-id>
Second copy under Documents with the same ID folder layout. OneDrive backup can sync or lock this tree, so check it separately when saves go missing after a cloud sync.
<SteamLibrary>/steamapps/compatdata/2091020/pfx/
Steam Play prefix for the Steam release. Both Windows MercurySteam trees are mirrored inside the prefix drive. Useful on Deck or Linux where the Documents path maps differently.
Frequently asked questions
How do I move Blades of Fire saves to a new PC?
Copy both MercurySteam trees: %LOCALAPPDATA%\MercurySteam\Blades of Fire and %USERPROFILE%\Documents\MercurySteam\Blades of Fire. Each holds a folder named with your hex user ID. Grab the whole ID folder on both sides with the game closed.
What is the long hex folder inside Blades of Fire?
It is your account ID in hex, assigned per store. The publisher's own example shows a long string like 62305ca4d06b45dca9983f0ec950e88a. Never type someone else's ID folder name by hand. Use the one already on your disk.
Does OneDrive affect Blades of Fire saves?
Yes. That copy means OneDrive can move or lock your saves if Documents backup is on. If progress vanishes after a OneDrive sync, check OneDrive's version history or exclude Documents from backup and keep the Local copy as master.
