Where Are Assassin's Creed Black Flag Resynced Save Files Located?
Black Flag Resynced splits saves between Ubisoft Connect numeric folders and a Documents config, with store-specific save IDs.
Last updated
Black Flag Resynced is the 2026 remake, and it saves like a modern Ubisoft title rather than the 2013 original: progress goes through Ubisoft Connect's savegames tree, inside a numeric folder per account, while configuration lives separately in Documents\Assassin's Creed Black Flag Resynced\ACBlackFlag.ini.
The numeric folder depends on where you bought the game. Steam builds write under 66088, Ubisoft Connect builds under 65043, and both sit inside the same savegames\[User-ID] parent. There is also a local Ubisoft\Assassin's Creed Black Flag Resynced\save folder under Local AppData. Steam Cloud is not listed; Ubisoft's own cloud covers the saves, so the local folders are what you copy for offline peace of mind.
Where Assassin's Creed Black Flag Resynced stores this, by platform
%LOCALAPPDATA%\Ubisoft\Assassin's Creed Black Flag Resynced\save
Local save data written by Ubisoft Connect. Copy with the game and the launcher closed; cloud sync can overwrite manual restores.
<Ubisoft-Connect-folder>\savegames\<user-id>\65043
Ubisoft Connect store builds use 65043; Steam builds use 66088 in the same parent. [User-ID] is your Ubisoft account number. Keep the numeric folder whole when moving saves.
%USERPROFILE%\Documents\Assassin's Creed Black Flag Resynced\ACBlackFlag.ini
Graphics and control configuration, separate from saves. Note this is Documents, unlike the save tree. OneDrive redirection can move it, so check both if it looks missing.
Frequently asked questions
Do the 2013 Black Flag save guides work for Resynced?
No. The original stores saves differently, and the remake routes everything through Ubisoft Connect's savegames tree with numeric store IDs. Use this post for Resynced and keep the old guide only for the original game.
Which numeric save folder is mine, 65043 or 66088?
Ubisoft Connect builds use 65043 and Steam builds use 66088 inside the same savegames\[User-ID] parent. Open both and match by file dates if you are unsure which store your copy came from.
Does Resynced have cloud saves?
Ubisoft's cloud covers saves rather than Steam Cloud, which is not listed for the game. For restores, close the game and launcher, keep a local copy before syncing back, and let the newer version win on the next launch.
