## Description

Advanced filesystem operations server for Claude Desktop with large file handling capabilities and Claude-optimized features. Built by efforthye with TypeScript, it provides streaming-based writing for files of any size, auto-chunking for memory-efficient operations, sequential reading with continuation token support, and comprehensive file management including copy, move, delete, batch operations, and archive compression/extraction. The implementation includes sophisticated editing tools for precise line-based modifications, backup and recovery mechanisms, retry logic with exponential backoff, and smart exclusions for system files, making it particularly useful for developers working with large codebases, data processing workflows, and automated file operations that require reliable handling of substantial file sizes without memory overflow.
