This is a minimalistic PHP-based file storage system with:

• Password-protected admin panel
• Chunked file upload for large files (GB+)
• Upload progress display
• File listing with download and delete options
• Direct link copy button
• No external libraries required

🚀 Features

• Chunked upload via JavaScript + fetch
• Server-side chunk handling and merging
• No CSS or frontend frameworks
• Fully self-contained (no Composer needed)

🛠 Requirements

• PHP 7.4+
• A web server (or use PHP's built-in server)

📁 Folder Structure

/simple-file-share/
├── index.php
├── upload/             # Final uploaded files
├── upload_chunks/      # Temporary chunk storage
├── upload_chunk.php
├── merge_chunks.php
└── config.php          # Configuration (password and paths)

🔐 Configuration

Create config.php:

<?php
define('PASSWORD', 'your_password_here');
define('UPLOAD_DIR', __DIR__ . '/upload/');
define('CHUNK_DIR', __DIR__ . '/upload_chunks/');

▶️ Run the Server

Use PHP's built-in server:

php -S localhost:8000

Then open:

http://localhost:8000

📤 Uploading Files

• Select a file in the UI.
• It is split into 1MB chunks (adjustable in JS).
• Upload progress is shown.
• File is merged server-side and available for download.

🧹 Cleanup

• Temporary chunk files are automatically deleted after merging.
• Files can be deleted via the admin interface.
