ComfyUI Grover Nodes

Open Path Node 📁

A custom ComfyUI node that provides an easy way to open file and folder paths in your system's default file explorer.

Features

• Cross-platform support: Works on Windows, macOS, and Linux
• Smart path handling: Automatically detects whether the path is a file or folder
• File selection: On Windows, if you provide a file path, it will open the folder and select the file
• Simple interface: Just enter a path and click the "📁 Open Path" button

Usage

1. Add the "📁 Open Path" node to your workflow
2. For manual paths: Enter a file or folder path in the text input field
3. For dynamic paths: Connect any node that outputs a string path to the "path" input
4. For dynamic paths: Execute the workflow first (click "Queue Prompt") to compute the path values
5. Click the "📁 Open Path" button to open the location in your system's file explorer

Important Note for Dynamic Paths

When using connected inputs (like from Save Image, Load Image, or text processing nodes), you must execute the workflow first before the Open Path button will work. This is because dynamic paths are only computed during execution.

Workflow for dynamic paths:

1. Connect your path-generating node → Open Path node
2. Click "Queue Prompt" to execute the workflow
3. After execution completes, click "📁 Open Path" button
4. The computed path will be opened in your file explorer

Supported Path Types

• Absolute paths: C:\Users\YourName\Documents\file.txt (Windows) or /home/username/documents/file.txt (Linux/macOS)
• Relative paths: ./outputs/image.png
• Folder paths: Any valid directory path
• File paths: Any valid file path

Platform-Specific Behavior

• Windows: Uses explorer.exe with /select for files to highlight them
• macOS: Uses the open command
• Linux: Uses xdg-open with fallbacks to common file managers (nautilus, dolphin, thunar, pcmanfm)

Error Handling

The node will show error messages if:

• The path doesn't exist
• The path is empty
• The system cannot open the file explorer
• Network errors occur when communicating with the backend

Installation

1. Clone or download this repository to your ComfyUI custom_nodes directory
2. Restart ComfyUI
3. The node will appear under the "Grover/System" category

Technical Details

This node consists of:

• Backend: Python node that handles the file system operations
• Frontend: JavaScript component that provides the button interface
• API: HTTP endpoint for communication between frontend and backend
