Overview and Save Behavior (Global Settings)
Global Settings is the central configuration panel in FMX for Windows. Every aspect of your photo booth setup -- camera, devices, cloud sync, theming, sharing, and more -- is managed from this single panel. Understanding how settings are saved (and when they are not) will help you avoid losing configuration changes.
Accessing Global Settings
- Press Ctrl+O on your keyboard, or click the Settings icon in the FMX interface.
- Global Settings opens as a full-screen panel with tabs along the left side.
Save Behavior
FMX uses a preview-then-save model for Global Settings:
- Immediate preview -- As you change a setting, FMX applies it to the running application right away so you can see the effect. However, the change is not yet persisted to disk.
- Save Changes button -- You must click the Save Changes button at the bottom of the panel to write your changes to disk. Until you do, changes exist only in memory.
- Unsaved changes are lost on exit -- If FMX is closed or crashes before you click Save Changes, any modifications made since the last save are discarded.
Tip: Save frequently. After adjusting a group of related settings, click Save Changes before moving to the next tab. This protects your work in case of an unexpected restart or crash.
Exception: Event Selection
The Event selection is the one setting that auto-saves immediately when changed. You do not need to click Save Changes after selecting a different event -- the change takes effect and is persisted right away.
Settings Storage
All Global Settings are stored in the file appsettings.json located in your FMX base folder (the folder configured in the Storage tab). This is a plain JSON file and can be backed up or transferred between machines, though editing it manually is not recommended.
Tab Overview
Global Settings is organized into the following tabs:
| Tab | Purpose |
|---|---|
| About | Version info, license status, and logout |
| Camera | Camera device selection and capture settings |
| Cloud | Cloud sync toggles and QR code configuration |
| Devices | Printers, microphone, LED ring, key fob, sensors, and payment terminals |
| Experience | Auto-start, idle timeout, and corner shortcuts |
| Sharing | Email and SMS provider configuration |
| Storage | Base folder, auto-delete, and logging settings |
| Theme | Colors, branding, asset management, and UI text |
