GD Storage

Hide any file inside a Geometry Dash level

Features • Installation • Usage • How It Works • Configuration • Acknowledgments • License

Features

• Upload to GD Servers - Store files on RobTop's servers, get a level ID to share
• Fetch from GD Servers - Download and decode files using just a level ID
• Local Save Support - Inject encoded levels directly into your GD save file
• Cross-Platform - Works on Windows, macOS, and Linux (via Proton)
• Configurable - Custom GD save paths for non-standard installations
• Secure - Path traversal protection, input validation, overwrite confirmation

Installation

Requires Python 3.10+

pip install gd-storage

Or install in development mode:

git clone https://github.com/c4k3ss/GD-Storage
cd GD-Storage
pip install -e .

Usage

# Upload a file to GD servers
gd-storage --upload photo.png

# Download and decode from GD servers
gd-storage --fetch 123456789

# Encode and inject into local GD save
gd-storage --encode document.pdf

# Decode from local GD save
gd-storage --decode "LevelName"

# Configure GD save path (for non-standard installations)
gd-storage --config

How It Works

Files are encoded using a base-9999 group encoding method:

1. Compression - The file is gzip compressed with the filename prepended
2. Chunking - Binary data is split into 8-byte chunks
3. Base Conversion - Each chunk is converted to 5 base-9999 numbers (1-9999)
4. Object Encoding - Numbers are stored in GD object group properties
5. Level String - Objects are serialized into a valid GD level string

Why Base-9999?

GD supports 10 groups per object (1-9999). By treating group numbers as digits in a base-9999 number system, we can efficiently pack 8 bytes into just 5 group values, achieving ~62.5% space efficiency.

Configuration

On first run, GD Storage auto-detects your save path:

• Windows: %LOCALAPPDATA%\GeometryDash
• macOS: ~/Library/Application Support/GeometryDash

For custom paths (Linux/Proton, custom installs), run:

gd-storage --config

Config is saved to ~/.config/gd-storage/config.json

Platform Support

Platform	Local Save	Upload/Fetch
Windows	Yes	Yes
macOS	Yes	Yes
Linux	Yes*	Yes

*Linux requires configuring the Proton GD save path manually

Dependencies

• dashlib - GD server API
• gdparse - GD level string parsing
• pycryptodomex - AES encryption for macOS saves
• zstandard - Zstandard compression

Save file handling is based on a modified version of PyCCGameManager.
