Basic File Operations

#include "incipe.h"

void setup() {
  incipe.init();
  /* USER CODE BEGIN 1 */
  Serial.begin(115200);
  // Create and write to a file
  incipe.writeFile(SPIFFS, "/data.txt", "Hello, World!");

  // Append data
  incipe.appendFile(SPIFFS, "/data.txt", "\nNew data");

  // Read file
  incipe.readFile(SPIFFS, "/data.txt");

  incipe.renameFile(SD, "/data.txt", "/signal.txt");
  /* USER CODE END 1 */
}

void loop {
  /* USER CODE BEGIN 2 */
  /* USER CODE END 2 */
}

Directory Management

// Create nested directories
incipe.createDir(SD, "/config");
incipe.createDir(SD, "/config/settings");

// List all files (recursively)
incipe.listDir(SD, "/", 2);  // 2 levels deep

// Remove specific directory
incipe.removeDir(SD, "/config");

Troubleshooting

Error	Solution
`Failed to open file`	Check path exists or storage is mounted
`mkdir failed`	Verify write permissions / storage space
Slow writes	Use smaller buffers (512B-1KB)
