How to Map SFTP as a Network Drive in Windows: A Native Approach for Developers


2 views

Windows Vista and Windows 7 introduced a convenient feature allowing users to map FTP servers as network drives through Windows Explorer. This functionality can be accessed by:

  1. Opening Windows Explorer
  2. Right-clicking on "Computer"
  3. Selecting "Map network drive"
  4. Entering the FTP address (e.g., ftp://example.com)

While this works well for standard FTP connections, developers often need secure SFTP (SSH File Transfer Protocol) access. The native Windows solution doesn't support SFTP due to:

  • Different protocol stack (SSH vs. FTP)
  • Encryption requirements
  • Authentication mechanisms

Here are some approaches to achieve SFTP drive mapping in Windows:

1. Using Third-Party Tools

Several reliable third-party solutions can bridge this gap:

// Example using WinSCP scripting
option batch abort
option confirm off
open sftp://username:password@example.com -hostkey="ssh-rsa 2048 xx:xx:xx..."
net use Z: \\\\sshfs\\example.com /user:username password

2. SSHFS for Windows

Dokany (formerly Dokan) with SSHFS provides a filesystem implementation:

  1. Install Dokany library
  2. Install SSHFS-Win
  3. Mount using command line:
    sshfs user@example.com: Z: -o StrictHostKeyChecking=no

3. WebDAV Alternative

If the server supports WebDAV over HTTPS:

net use Z: https://example.com/webdav /user:username password

For developers needing automation:

# PowerShell script to mount SFTP via WinSCP
$sessionOptions = New-Object WinSCP.SessionOptions -Property @{
    Protocol = [WinSCP.Protocol]::Sftp
    HostName = "example.com"
    UserName = "username"
    Password = "password"
}

try {
    $session = New-Object WinSCP.Session
    $session.Open($sessionOptions)
    $session.MapNetworkDrive("Z:")
}
catch {
    Write-Error "Error: $_"
}

When implementing these solutions:

  • Always use key-based authentication when possible
  • Store credentials securely using Windows Credential Manager
  • Consider using VPN for additional security layer

For better performance with large files:

# WinSCP performance tuning
option transfer binary
option sync browsedirs
preferences cache=1M

While Windows Vista/7+ does provide native FTP drive mapping through Explorer's "Map Network Drive" feature (via ftp:// URLs), this implementation has critical limitations for developers:

  • Only supports plain FTP (port 21) without encryption
  • No native SFTP (SSH File Transfer Protocol) support
  • Authentication limited to basic credentials

SFTP (SSH File Transfer Protocol) runs over SSH (port 22) and provides:

// Sample SFTP connection parameters
Host: sftp.example.com
Port: 22
Protocol: SSH-2
Authentication: PublicKey/Password
Encryption: AES-256

Common developer use cases requiring SFTP:

  • Secure deployment to cloud servers
  • Editing remote files through IDE integrations
  • Automated CI/CD pipeline transfers

Option 1: WinFsp + SSHFS-Win

The most robust native-like solution:

# PowerShell installation
choco install winfsp
choco install sshfs-win

# Mount command
net use Z: \\sshfs\user@host\path /persistent:yes

Option 2: Dokan Library + SFTP Net Drive

Commercial alternative with GUI configuration:

1. Install SFTP Net Drive
2. Configure connection:
   - Host: sftp.example.com
   - Port: 22
   - Authentication: Private Key
3. Assign drive letter (e.g. S:)

Once mapped, treat like local filesystem:

// C# file operations example
string remotePath = @"S:\projects\config.json";
string content = File.ReadAllText(remotePath);

// Python example
with open("Z:/logs/app.log", "a") as f:
    f.write("New log entry")
  • Always use SSH keys instead of passwords
  • Set appropriate file permissions (chmod 600 for private keys)
  • Regularly rotate credentials
