Schedule 1 Save Support (S1SS)

S1SS is a PowerShell script that helps you manage your Schedule 1 save files on Windows. It can:

• List all your saves with key stats at a glance
• Back up any active save to an unlimited local vault
• Restore a vaulted save back into any game slot (1–5)
• Delete saves from active slots, the vault, or stray folders in the game's save directory
• Clean up unexpected folders that end up in the game's Saves directory

What it does not do: S1SS does not modify save file contents. Backup and restore are straight file copies. There is no in-place editing of game data in this version.
