n8n-nodes-windows-smb2

> [!NOTE]
> This project is a fork/copy of n8n-nodes-windows-network-fileshare-smb2 with additional features like encoding selection.

This is an n8n community node. It lets you use Windows SMB2 in your n8n workflows.

Windows Smb2 allow you to access files and directories on Windows servers and network-attached storage devices using the SMB2 protocol. This node enables seamless file operations across your network infrastructure.

n8n is a fair-code licensed workflow automation platform.

Installation

Follow the installation guide in the n8n community nodes documentation.

Install using the package name:

n8n-nodes-windows-smb2

Operations

This node supports comprehensive file and directory operations on Windows network shares:

File Operations

• Read File – Download and read file contents from the network share
• Write File – Upload or create files with specified content
• Delete File – Remove files from the network share
• Move File – Rename or relocate files within the share
• Copy File – Copy files from one share to another
• File Metadata – Get file size, existence, and other metadata

Directory Operations

• List Directory – Enumerate files and folders in a directory
• Create Directory – Create new folders on the network share
• Delete Directory – Remove empty directories from the share

Credentials

To use this node, you need access to a Windows network file share with appropriate permissions.

Prerequisites

• Access to a Windows file share (SMB2 compatible)
• Valid Windows domain or local user credentials
• Network connectivity to the target share

Authentication Setup

1. In n8n, create new credentials of type “Windows SMB2 API”
2. Configure the following fields:
– Share Path – UNC path to your network share (e.g., \serversharename)
– Domain – Windows domain name (leave empty for local accounts)
– Username – Windows username with share access
– Password – User password
– Connection Timeout – Timeout in milliseconds (default: 30000)

Required Permissions

Your user account needs the following permissions on the target share:

• Read permissions for file read and directory list operations
• Write permissions for file write and directory create operations
• Delete permissions for file and directory deletion operations

Compatibility

• Minimum n8n version: 1.0.0
• Tested with: n8n 1.x
• Node.js requirement: 20.15 or higher
• SMB Protocol: SMB2 and SMB3 compatible shares
• Operating Systems: Windows, Linux, macOS (client-side)

Known Limitations

• Requires --openssl-legacy-provider flag for Node.js compatibility
• Large file operations may require timeout adjustments
• Some legacy SMB1 shares may not be supported

Usage

Basic File Operations

1. Add the “Windows SMB2” node to your workflow
2. Configure your Windows Network credentials
3. Select the desired operation (File or Directory)
4. Specify the file/directory path relative to your share root
5. Configure operation-specific parameters

Path Format

• Use forward slashes / or backslashes in paths
• Paths are relative to your configured share root
• Example: folder/subfolder/file.txt or foldersubfolderfile.txt

Error Handling

The node provides detailed error messages for common issues:

• Authentication failures
• Network connectivity problems
• File not found errors
• Permission denied errors

Configure error handling in your workflow using n8n’s built-in error handling features.

Development

This section contains information for developers who want to contribute to or modify this node.

Prerequisites

• Node.js 20.15 or higher
• npm or yarn package manager
• TypeScript knowledge
• Basic understanding of n8n node development

Setup Development Environment

1. Clone the repository:

   git clone https://github.com/hernanjh/n8n-nodes-windows-smb2.git
   cd n8n-nodes-windows-smb2
   

2. Install dependencies:

   npm install
   

3. Set up environment variables for testing:

   # Create .env file with your test credentials
   SMB_SHARE=\\server\sharename
   SMB_DOMAIN=YOURDOMAIN
   SMB_USERNAME=testuser
   SMB_PASSWORD=testpass
   

Development Commands

Build the node
npm run build
Development mode with watch
npm run dev
Run linting
npm run lint
Fix linting issues
npm run lintfix
Format code
npm run format
Run tests
npm run test

Testing

The project includes comprehensive testing:

• SMB2 Package Tests – Direct testing of the @marsaud/smb2 package functionality
• n8n Node Tests – Integration tests for the complete node implementation

Run tests with:

npm run test:operations  # Test SMB2 package directly
npm run test:node        # Test n8n node implementation
npm run test            # Run both test suites
