-This examples demonstrates the usage of the "Arduino_UnifiedStorage" library,
-which allows the program to easily switch between different storage mediums.
+    SimpleStorageWriteRead
 
-By uncommenting the appropriate lines, you can choose to use either an SD card, 
-a USB storage device, or internal storage as the storage medium. 
+    Demonstrates basic usage of the "Arduino_UnifiedStorage" library to write and read data to storage.
+    Supports SD card, USB storage, and internal storage (default, uncomment to choose).
 
-The example code is set up to use an SD card by default.
+    n the setup function, the code initializes serial communication, mounts the storage medium,
+    creates a root directory with three subdirectories, and writes data to three files in each subdirectory.
 
-In the setup function, the code initializes the serial communication and checks if the storage medium is successfully mounted. 
-It then creates a root directory and three subdirectories within it.
-After creating the subdirectories, the code creates three files inside each subdirectory and writes data to them.
+    Following this, the code showcases reading data from files by using "seek" and "available" methods,
+    switching file modes to read, resetting file pointers to the start,
+    and printing the read data to the serial monitor using a while loop.

-Next, the code demonstrates how to read data from the files using the "seek" and "available" methods.
-It changes the mode of the files to read mode, moves the file pointers to the beginning, and reads the data from each file using a while loop.
-The read data is printed to the serial monitor.
