What is a SAVE1 file?

SAVE1 files mostly belong to Koikatu. Your SAVE1 file is a specialized game save file used by a school simulation game from Koikatu. It is stored as a ZIP archive, which means the game progress data and settings are compressed inside it.

Purpose: It holds your current game state and settings.

Internal Structure: Although it appears as a save file, its content uses a standard ZIP format.

Access Method: You can rename the file’s extension to .zip and open it with common archiving tools like WinRAR or 7-Zip.

Altering these files directly may corrupt your game data, so proceed with caution.
