Detailed Description

Experimental NVS-based file system interface for ESP32.

Provides a file system compatible interface using ESP32's NVS (Non-Volatile Storage) as the backend. This allows NVS to be used as a drop-in replacement for SPIFFS or LittleFS in applications that require faster access times and better wear leveling.

Warning

This is an experimental implementation with the following limitations:

• Missing exists() method for file existence checking
• Missing gc() method for garbage collection compatibility
• Error handling in open() method needs improvement
• No support for directory operations

Advantages over traditional file systems:

• Faster read/write operations (no file system overhead)
• Built-in wear leveling and atomic operations
• Better suited for configuration data and small files
• No file system mounting/unmounting required

Limitations:

• Maximum 15-character file names (NVS key limitation)
• No hierarchical directory structure
• Less suitable for large files or binary data
