Step-by-Step Tutorial: How to Set Up DeDupler duplicate files clutter hard drives, waste valuable storage space, and slow down system backups. DeDupler is a lightweight, open-source command-line tool designed to safely scan, identify, and remove duplicate files across various directories.
This guide covers the entire setup process, from installation to running your first deduplication scan. Scenario 1: Setting Up DeDupler via Package Managers
This method is ideal for users who prefer quick installations and automatic updates through standard system package managers. 1. Install the Software macOS: Open Terminal and run brew install dedupler.
Linux (Ubuntu/Debian): Run sudo apt update && sudo apt install dedupler.
Windows: Open PowerShell as Administrator and run winget install dedupler. 2. Verify the Installation Open your terminal or command prompt. Type dedupler –version and press Enter. Confirm the screen displays the version number. Scenario 2: Setting Up DeDupler from Source (Advanced)
This method suits developers or users running platforms where pre-compiled binaries are unavailable. It requires Python 3.8+ and Git installed on your system. 1. Clone the Repository Open your terminal. Run git clone https://github.com. Navigate into the directory using cd dedupler. 2. Install Dependencies Create a virtual environment using python -m venv venv.
Activate it via source venv/bin/activate (Mac/Linux) or .\venv\Scripts\activate (Windows). Run pip install -r requirements.txt to load dependencies. Build the application locally by running pip install .. Scenario 3: Running Your First Configuration and Scan
Once installed, configure DeDupler to safely analyze your target folders. 1. Initialize the Configuration File Run dedupler –init in your terminal.
This creates a hidden configuration file (.deduplerrc) in your home directory.
Open this file in any text editor to modify default behaviors.
Set your preferred hashing algorithm (e.g., MD5 for speed, SHA-256 for accuracy). 2. Run a Safe “Dry Run” Scan Never delete files without testing first. Execute dedupler –scan /path/to/target/folder –dry-run.
Review the generated console report showing discovered duplicates. Check that no critical system files are listed in the logs. 3. Execute the Final Deduplication Run dedupler –scan /path/to/target/folder –delete.
Alternatively, use –move /path/to/archive to quarantine duplicates safely.
Wait for the completion summary to see how much disk space you reclaimed.
