Syncfusion File Manager SDK 2026 Volume 3 (35.1.37)Major versionSep 29, 2026
Features
  • Web File Manager
    • Prevent folders from opening during drag and drop (React, Angular, JavaScript, ASP.NET Core, Vue, ASP.NET MVC) - Users can control which interactions open folders. They can prevent folders from opening during drag-and-drop operations while still allowing them to open for other interactions, such as double-clicking, keyboard navigation, or context menu actions.
    • WebMCP integration (React, Angular, JavaScript, Vue) - The File Manager supports the Web Model Context Protocol (WebMCP), enabling AI models and agents to interact with files and folders through built-in tools. Write operations require user confirmation, and the beforeWebMcpToolExecute event lets users inspect, modify, or cancel tool execution.
