# Minimal Chunked File Storage (PHP)

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
<?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:

```bash
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.
