Assassin's Creed IV: Black Flag stores its save files at {UBISOFT}\437 on Windows. Checkpoint64 already knows this folder — it backs it up automatically and keeps every version, so a corrupted or overwritten save is one click from restored.
Where Assassin's Creed IV: Black Flag saves are stored
- Windows —
{UBISOFT}\437
or{UBISOFT}\273
Where two locations are listed, which one is in use depends on the install (Checkpoint64 checks them in order and uses the first that exists).
How to open the save folder
- Windows — press Win+R, paste
{UBISOFT}\437, and press Enter.
Backing up Assassin's Creed IV: Black Flag saves automatically
- Install Checkpoint64 (free) and pick Assassin's Creed IV: Black Flag — the save path above is already preset.
- Auto-backup watches the folder and uploads a new version whenever it changes, keeping full history.
- Restore any version in one click if a save corrupts, gets overwritten, or a mod breaks it.
