BACH FileCommander
Gives Claude full filesystem access plus process and shell session management through 44 tools. You get safe deletes that route to Recycle Bin or Trash, async background search across large directory trees, interactive REPL sessions for Python or Node, and string-based file editing with context validation. Also handles format conversion between JSON, CSV, YAML, TOML, and XML, creates and extracts ZIP archives, runs OCR on images via tesseract.js, and exports Markdown to PDF through a headless browser. Includes cloud-lock diagnosis for OneDrive and similar sync services that block rename operations. Cross-platform with platform-specific optimizations for Windows, macOS, and Linux.
