Settings and Data

The Settings page

Open it with Ctrl+5.

Section	What it holds
Engine	The folder with llama-server.exe, a Test button, and the detected version and GPUs. See Building the Engine.
Models	The models folder, and whether loading a model unloads the previous one (on by default). See Model Library.
Default load settings	Load settings used for models that have none of their own. Press Save load defaults to apply. See Loading Models.
New chats	The default system prompt, sampling values (temperature, top P, top K, min P, repeat penalty) and thinking settings for new chats, and whether reasoning blocks start expanded. Existing chats keep their own settings.
Appearance	Dark, Light or System. The sun/moon button in the top bar switches between dark and light quickly. Also Minimize to system tray and Close to system tray (both off by default); see Running in the system tray.
Keyboard shortcuts	See Keyboard Shortcuts.
About	The app version and a button that opens the data folder.

Some settings live on the page they belong to rather than here:

• MCP Tools page — tool use on or off, tool approval, tool loading mode and budget, shortening old tool results. See MCP Tools.
• Developer page — port, access, API key, idle unload. See Local API Server.
• Chat settings panel — system prompt, sampling, presets, structured output and what to do when the context fills up, for the current chat. See Chat.
• Load panel and My Models — per-model load settings. See Loading Models.

Running in the system tray

Two switches under Settings → Appearance let the app keep running out of the way, with loaded models and the Local API Server still working:

• Minimize to system tray — minimizing hides the window from the taskbar and shows a RulZ LLM Suite icon in the notification area (by the clock).
• Close to system tray — the window's close button (X) hides the window to the tray instead of quitting.

While the window is hidden:

• Click the tray icon to bring the window back. The icon disappears again once the window is showing.
• Right-click it for Show RulZ LLM Suite and Quit. Quit exits the app properly and stops any running models.
• Starting the app again (for example from the Start menu) also brings the hidden window back.
• Signing out of Windows or shutting down still closes the app normally.

If you turn both switches off while the window is hidden, it comes back by itself.

Where your data is stored

Everything the app saves is in %APPDATA%\RulZ LLM Suite (usually C:\Users\<you>\AppData\Roaming\RulZ LLM Suite). Settings → About → Open takes you there.

File or folder	Contents
settings.json	App settings, including the Developer page's API server settings
model-defaults.json	Saved load settings for individual models
presets.json	Chat presets
conversations\	One JSON file per chat
folders.json	The names of your chat folders
mcp.json	MCP server configuration
gguf-cache.json	Cached model metadata; safe to delete, it is rebuilt on the next scan
running-pids.json	Which llama-server processes the app started, so it can clean up after a crash

Your models are not stored here; they stay in your models folder, and the app never changes them except when you choose Move to Recycle Bin.

Things to know:

• Back up by copying the folder while the app is closed.
• The API key (Developer page) and any tokens in mcp.json (env and headers) are stored as plain text. Don't share these files or post them in an issue.
• Deleting a chat moves its file to the Recycle Bin, so a mistaken delete can be undone from Windows.
• To reset the app's settings, close it and delete settings.json. Chats, presets and models are untouched.
