Folder Duplicator

VS Code extension: Duplicate the currently open folder and open it in a new window.

Features

• Duplicate the current workspace folder alongside the original.
• Support custom naming of the new folder.
• Handles large folders with progress notifications.
• Customize exclude patterns via settings.

Usage

1. Open a folder in VS Code.
2. Open the Command Palette (Cmd+Shift+P / Ctrl+Shift+P).
3. Run "Duplicate Current Folder".
4. Enter a new folder name (or accept the suggested one).
5. After duplication completes, the folder opens in a new window automatically.

Settings

You can customize exclude patterns from VS Code settings:

{
  "folderDuplicator.excludePatterns": [
    "node_modules",
    ".git",
    "dist",
    "*.log",
    ".DS_Store"
  ]
}

By default, the exclude patterns list is empty (all files are copied).
