The confirmed full-release addition to the Safe Folder is keyBuy: it lets you decide whether to keep or sell leftover Keys. That makes the Safe Folder a resource decision, not an automatic instruction to sell everything. The feature is described in the developer's September release announcement.
Make the keep-or-sell decision
- Check how many Keys you have available.
- Consider whether you want to retain Keys for an Installer choice. Legendary Installers require three; Cracked Installers require none.
- Read keyBuy's current offer in the game.
- Keep or sell according to your next objective, rather than assuming one choice is always optimal.
The Installer requirements are official release facts. The decision checklist is editorial guidance: no tested best conversion rate or guaranteed future offer is claimed.

Do not mix Demo timing into release advice
The July 14 Demo update states that Safe Folders spawn closer and refers to a 30-second timer. It also discusses dragging the Safe Folder. Because that is a Demo changelog, this release guide does not promise the same timing or controls in every current run.
If you are deciding whether you can reach or use a Safe Folder, follow the cues in the running game. This page cannot supply a verified spawn coordinate, timer exploit or guaranteed survival window.
The Plugin guide covers how Keys fit into installation. The Protocol guide explains the separate difficulty choice. Checked September 30, 2026; this short page answers the confirmed keyBuy decision without inventing a full Safe Folder walkthrough.
