Where Are Hello Kitty Island Adventure Save Files Located?
The Hello Kitty Island Adventure save folder on PC, nested by numeric Steam ID with backups beside it.
Last updated
The PC version saves under Sunblink Entertainment in LocalLow, inside a Hello Kitty folder that holds one numbered subfolder per Steam account. Your island lives deepest in that tree, in a folder called Local with a file named save_0.save.
That numeric middle folder is your 64-bit Steam ID. A Backups folder sits next to it with earlier copies, which is genuinely useful because this is a game where a misclick can bulldoze hours of decorating.
Where Hello Kitty Island Adventure stores this, by platform
%USERPROFILE%\AppData\LocalLow\Sunblink Entertainment\Hello Kitty\Saves\[SteamID64]\Local
[SteamID64] is your 64-bit numeric Steam ID. The actual save is save_0.save in Local. A Backups folder beside Local holds older copies worth grabbing before risky edits or transfers.
Frequently asked questions
How do I transfer my island from Switch to PC?
Place your transferred save as save_0.save inside the Local folder for your numeric Steam ID. Players who tested this confirm the PC build reads it directly.
My island broke. Can I roll back?
Check the Backups folder next to Local. Copy an older backup over save_0.save while the game is closed and you return to that earlier state.
