Kingdom Come: Deliverance uses Windows’ Saved Games folder, which is easier to back up than many AppData layouts, but its nearby profile/configuration directory can create confusion about what actually contains progress. SaveEditor separates the saves tree from profile XML and recommends copying them for different purposes. The page also emphasizes build, DLC, and mod context: a structurally intact save can still fail if the installation that loads it no longer matches the environment that created it.
Known Kingdom Come: Deliverance save-file structure
The researched filename or folder pattern is Profile/campaign save files below the saves tree; configuration profiles live separately under Saved Gameskingdomcomeprofilesdefault.. File-extension context: No single extension is sufficient to identify every relevant save record. The documented format notes are: The game keeps saves under the Windows Saved Games known folder rather than AppData. Configuration/profile XML is nearby but outside the saves directory, so backup scope can be chosen deliberately.
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. A save can depend on the game version, DLC, or mod state. Restoring the file alone does not reproduce every external dependency. 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: %USERPROFILE%Saved Gameskingdomcomesaves. Storefront context: Steam, GOG, Epic Games Launcher, EA app, Microsoft Store. Multiple storefronts are documented, but the normal Windows save root is shared. Cloud services can still restore a conflicting copy. 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
Back up the entire kingdomcomesaves directory. If preserving user configuration or mod-related profile settings too, copy profilesdefault separately so save data and settings remain distinguishable. 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, GOG Galaxy, Epic, EA, and Xbox cloud support are documented depending on storefront. 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 a restored save refuses to load, compare game build/DLC/mod state and check cloud synchronization before assuming the save bytes are damaged. Those questions require a verified parser/profile or a game-specific source, not a generic format guess.
