Что такое формат файла SAVE?
A .save file is a binary game save state created by id Software's id Tech 4 engine, used primarily in Doom 3 (2004). When the player saves their progress, the engine serializes the full world state - including the current map, player position and health, inventory, entity states, and script variables - into a .save file stored in the game's dedicated savegame folder.
The format is engine-internal and written in little-endian binary. Unlike text-based configurations or PK4 archives, .save files have no publicly documented file signature (magic bytes); the engine identifies them by their location in the save directory rather than by a header. A companion preview screenshot is written alongside each save entry so the game's save/load menu can display a thumbnail.
Save files are tightly version-locked: they are not portable between different builds or patches of the game, and editing them is unofficial and unsupported. On load, the id Tech 4 engine validates the file and rejects any corrupt or incompatible saves.
Beyond Doom 3, the same .save extension and engine format were used by other id Tech 4 titles including Quake 4 and Prey (2006). Open-source source ports such as dhewm3 can load original Doom 3 .save files on Linux and macOS.
Безопасность и защита
РИСК: LOWA Doom 3 .save is passive game data that only the game loads; it cannot execute on its own. Risks are practical, not malware: saves are tied to the game build (copying between mismatched versions can fail), and unofficial save editors can corrupt the file. Keep a backup before editing. Be wary of "universal save editor/converter" download sites, which are often adware.
Детали формата
в двух словах- Generic application/game save state - Many other games and programs write .save files; format is entirely app-specific and only the originating program can read it.
- GNU nano emergency save (.save) - nano appends .save to a filename when it dumps a buffer on a crash; it is plain text, not a Doom save.
