Detailed Description

Experimental file-like interface for NVS storage operations.

Provides a file system compatible interface for NVS operations on ESP32. This class mimics the behavior of file handles used by SPIFFS and LittleFS, allowing NVS to be used as a drop-in replacement for traditional file systems.

Warning

This is an experimental implementation. The following limitations exist:

• Missing size(), position(), and readBytes() methods required by Storage class
• No default constructor for temporary object creation
• Limited error handling in some operations
• Memory management in _loadData() needs improvement

Key differences from traditional file systems:

• File paths are converted to NVS keys (max 15 characters)
• No concept of file position or streaming reads
• Atomic write operations (all-or-nothing)
• Built-in wear leveling and data integrity
