What potential pitfalls should be considered when using sessions to manage file storage in PHP?

One potential pitfall when using sessions to manage file storage in PHP is the risk of session data being lost or corrupted, leading to potential data loss. To mitigate this risk, it is important to properly handle session initialization, saving, and destruction. 

// Start session
session_start();

// Store file data in session
$_SESSION['file_data'] = $fileData;

// Save session data
session_write_close();

// Retrieve file data from session
$fileData = $_SESSION['file_data'];

// Destroy session
session_destroy();
