Dragon’s Dogma 2 deliberately maintains more than one save concept. The Steam `win64_save` folder includes the current save, an inn/rest slot, and settings/context records. That means a one-file backup can be misleading when the goal is a full rollback. SaveEditor.com recommends copying the entire folder before experimentation and labeling the backup by date. Steam Cloud should be considered part of the restore plan so it does not immediately reintroduce an unwanted remote revision.
Known Dragon's Dogma 2 save-file structure
The researched filename or folder pattern is data000.bin
data001Slot.bin
ssdata00-1.bin. File-extension context: .bin The documented format notes are: Steam PC saves live under the win64_save directory. Community/Steam documentation consistently identifies data000.bin as the current save, data001Slot.bin as the inn/rest slot, while ssdata00-1.bin stores settings-related data.
Why an extension is not enough
A save filename can identify a likely container, but it does not prove the internal schema, game version, checksum rules, encryption state, or editability. The game maintains different save concepts, including the current save and inn-rest slot. Replacing one without understanding the other can produce confusing rollback behavior. SaveEditor therefore separates file identification from Tool compatibility and only labels a game-specific Tool Verified when its exact profile/version evidence passes the runtime gate.
Where the format is stored
PC save locations: Windows: Steam: <Steam-folder>userdata<user-id>2054970remotewin64_save | Linux / Steam Play: Steam Play: <SteamLibrary-folder>/steamapps/compatdata/2054970/pfx/. Storefront context: Steam. The save is under Steam userdata rather than the game installation directory. The numeric user folder is account-specific. This matters because two releases can use different containers or companion files even when the visible slot name is similar.
Back up before inspecting or editing
Copy the complete win64_save folder before any rollback. Keep data000.bin and data001Slot.bin together with the settings/context files rather than assuming one file is the whole profile. A read-only viewer is lower risk than a writer, but the live save should still be copied first. Cloud context also matters: Steam Cloud can synchronize the win64_save records. A rollback should be planned so cloud sync does not immediately restore the copy you were trying to replace. Keep the original bytes available so any experiment can be reversed without relying on a cloud service or automatic backup.
What this reference does not claim
This page does not infer an undocumented checksum algorithm, encryption key, compression layer, or cross-store conversion from the file extension. Troubleshooting evidence: If testing a restore, preserve the live folder and coordinate Steam Cloud state first. Do not delete files merely to start over without a dated backup. Those questions require a verified parser/profile or a game-specific source, not a generic format guess.
Verification context: The Steam userdata location was reviewed against PCGamingWiki. Filename roles were cross-checked against long-running Steam community documentation for the PC release.
