📚 Usage Tutorial (Cookbook)

🍳 Recipe 1: Creating Your First Update Package

Let's create a differential update package step by step!

Scenario: You have version 1.0.0 of your app and want to update it to version 2.0.0

Step 1: Prepare Your Directories

You need three folders:

• App Directory (📂 Old Version): Contains your version 1.0.0 files
• Release Directory (📂 New Version): Contains your version 2.0.0 files
• Patch Directory (📂 Output): Where the differential files will be saved

Example structure:
C:/MyApp/v1.0.0/     ← Old version
C:/MyApp/v2.0.0/     ← New version
C:/MyApp/patch/      ← Temporary output folder

Step 2: Open Packet Builder

1. Launch GeneralUpdate.Tools
2. Click on the "Packet" tab at the top
3. You'll see a form with several fields

Step 3: Configure Your Package

Fill in the fields:

Field	What to Enter	Example
Name	Package filename	MyApp_Update_v2.0.0
App Directory	Path to old version	C:/MyApp/v1.0.0/
Release Directory	Path to new version	C:/MyApp/v2.0.0/
Patch Directory	Temp output path	C:/MyApp/patch/
Format	Compression format	.zip (default)
Encoding	Text encoding	UTF-8 (recommended)

Step 4: Optional - Add Driver Files

If your update includes driver files:

1. Click "Select" next to "Driver Directory"
2. Choose the folder containing your driver files
3. They'll be automatically placed in a drivers/ folder inside the package

Step 5: Build the Package!

1. Click the "Build" button 🔨
2. Wait for processing (may take a few moments)
3. Success! 🎉 You'll see a message "Build success"
4. Your update package is saved in the parent directory of your Patch Directory

Result: You now have a .zip file containing only the changed files!

---

🍳 Recipe 2: Creating Version Configuration (OSS Packet)

Now let's create a version.json file that tells your application about available updates.

Step 1: Open OSS Packet Builder

1. Click on the "OSS Packet" tab
2. You'll see fields for version information

Step 2: Enter Version Information

Fill in the details for your update:

Field	What to Enter	Example
Version	Version number	2.0.0.0
Packet Name	Name of your .zip file	MyApp_Update_v2.0.0.zip
URL	Download URL	https://updates.myapp.com/packages/MyApp_Update_v2.0.0.zip
Date	Release date	2026-02-11
Time	Release time	16:30:00

Step 3: Calculate Hash (Security)

1. Click the "Hash" button 🔒
2. Select your .zip package file
3. The tool will calculate a SHA256 hash
4. This ensures the download wasn't corrupted or tampered with

Step 4: Add to Configuration

1. Click "Append" ➕ to add this version to the list
2. You can add multiple versions (version history)
3. The JSON preview will update automatically

Step 5: Save Configuration

1. Click "Build" button 💾
2. Choose where to save your version.json file
3. Success! You can now upload this file to your server

Result: You have a version.json file that looks like this:

[
  {
    "Version": "2.0.0.0",
    "PacketName": "MyApp_Update_v2.0.0.zip",
    "Url": "https://updates.myapp.com/packages/MyApp_Update_v2.0.0.zip",
    "Hash": "abc123def456...",
    "Date": "2026-02-11T16:30:00"
  }
]

🍳 Recipe 3: Packaging an Extension

Create a distributable extension package with metadata.

Step 1: Prepare Your Extension

Make sure you have:

• A folder containing your extension files
• Extension metadata (name, version, description)

Step 2: Open Extension Manager

1. Click on the "Extension" tab
2. You'll see a comprehensive form

Step 3: Fill Basic Information

Field	What to Enter	Example
Name	Extension identifier	MyAwesomePlugin
Display Name	User-friendly name	My Awesome Plugin
Version	Version number	1.0.0.0
Description	What it does	Adds awesome features to your app
Publisher	Your name/company	Your Company Name

Step 4: Select Directories

1. Extension Directory: Click "Select" and choose your extension folder
2. Export Path: Click "Select" and choose where to save the package

Step 5: Configure Platform & Details

• Platform: Select target platform (Windows/Linux/MacOS/All)
• License: Enter license type (e.g., "MIT", "Apache-2.0")
• Categories: Enter categories separated by commas (e.g., "Tools, Productivity")

Step 6: Advanced Options (Optional)

• Dependencies: Enter required extension IDs (comma-separated)
• Min/Max Host Version: Specify compatible app versions
• Custom Properties: Add key-value pairs for extra metadata

Step 7: Generate Package

1. Click "Generate" button 🎁
2. Wait for compression
3. Success! Your extension package is created

Result: You get a .zip file like MyAwesomePlugin_1.0.0.0.zip containing:

• All your extension files
• A manifest.json with all the metadata

❓ Frequently Asked Questions (FAQ)

Q: What's the difference between "Packet" and "OSS Packet"?

A: Think of it this way:

• Packet Builder creates the actual update files (the .zip package)
• OSS Packet Builder creates the configuration that tells where to download it

You need both! First create the package, then create the configuration file.

Q: Do I need to include all files in the update package?

A: No! That's the beauty of differential updates. The tool automatically:

1. Compares old vs. new versions
2. Only includes changed/new files
3. Removes deleted files during update

This saves bandwidth and speeds up downloads! 🚀

Q: What is the Hash field for?

A: The hash is like a fingerprint for your file. It ensures:

• ✅ File wasn't corrupted during download
• ✅ File wasn't tampered with
• ✅ Users get exactly what you published

Always calculate and include the hash for security!

Q: Can I use this for commercial projects?

A: Yes! The project uses Apache 2.0 license, which allows commercial use. See LICENSE for details.

Q: What platforms are supported?

A: The tool runs on:

• ✅ Windows 10 and later
• ✅ Linux (Ubuntu, Debian, Fedora, etc.)

Generated packages can target:

• ✅ Windows
• ✅ Linux
• ✅ MacOS (via Extension Manager)
