Where Are The Hundred Line: Last Defense Academy Save Files Located?
The Hundred Line save folder on PC, kept inside the game's own install directory instead of AppData.
Last updated
The Hundred Line breaks the usual rules and saves inside its own Steam install folder, under gamedata and savedata. If you only ever search AppData and Documents, you will never find it.
Saves sit in numbered files under a folder named after your numeric Steam ID. That placement has one practical consequence: verifying game files or moving the install can disturb saves, so keep a separate backup outside the Steam library.
Where The Hundred Line: Last Defense Academy stores this, by platform
C:\Program Files (x86)\Steam\steamapps\common\The Hundred Line -Last Defense Academy-\gamedata\savedata\[SteamID]
Inside the install folder, not AppData or Documents. [SteamID] is your numeric account ID with numbered .bin files inside. Start from your own Steam library path if you installed elsewhere, and back up outside the library before verifying files.
Frequently asked questions
Why is there no Hundred Line folder in AppData?
The game stores saves in its install directory under gamedata\savedata. That is unusual on PC but confirmed by the developers' own transfer guides.
Do demo saves carry into the full Hundred Line game?
Yes. Copy the savedata folder from the demo install into the full game's gamedata directory and progress carries over.
