Mist

Mist is a simple, modern folder size monitor for Windows. It helps you keep track of cache directories, temp folders, or any specific path, and notifies you when they grow too large.

Download

Download Latest Release

1. Download mist_x.x.x_x64-setup.exe from the releases page.
2. Run the installer and follow the prompts.
3. Launch Mist from the Start Menu.

Note: Windows may show a SmartScreen warning since the app is not code-signed. Click "More info" → "Run anyway" to proceed.

Features

Development

If you want to build from source or contribute:

Prerequisites

• Node.js (v20+ recommended)
• Rust (latest stable)
• Visual Studio C++ Build Tools (required for Windows development)

Setup

1. Clone the repository:

   git clone https://github.com/fastfingertips/mist.git
   cd mist

2. Install dependencies:

   npm install

3. Run in development mode:

   npm run tauri dev

4. Build for production:

   npm run tauri build

   The installer will be located in src-tauri/target/release/bundle/nsis/.

Important: Windows Notifications in Dev Mode

Note for Developers: Windows desktop notifications will not work when running the app in development mode (npm run tauri dev) or when launching the .exe directly. This is because Windows requires the application to be properly registered in the Start Menu.

To test notifications, you must install the app using the installer (mist_x.x.x_x64-setup.exe). This registers the app with Windows and enables notification functionality.
