Introduction
In this tutorial, you'll learn how to use TreeSize's command-line interface (CLI) to analyze disk space usage on Windows systems. This approach is particularly valuable when dealing with software that has changed its licensing model, such as TreeSize, which now requires subscription-based support for perpetual license users. Understanding how to work with TreeSize's CLI allows you to continue performing disk analysis without relying on the GUI, which might be restricted or require a subscription.
Prerequisites
- Windows operating system (Windows 7 or later)
- TreeSize installed on your system (any version that supports CLI)
- Basic understanding of Windows command prompt
- Administrative privileges to run certain commands
Step-by-Step Instructions
Step 1: Locate TreeSize CLI Executable
First, you need to find the TreeSize command-line executable. The CLI tool is typically located in the TreeSize installation directory, often found at C:\Program Files\TreeSize\ or C:\Program Files (x86)\TreeSize\.
cd "C:\Program Files\TreeSize\"
Why this step is important: The CLI executable is usually named TreeSizeCmd.exe or similar. Knowing where to find it ensures you can execute commands without issues.
Step 2: Verify TreeSize CLI Installation
Once you're in the correct directory, verify that the CLI tool is available:
TreeSizeCmd.exe /?
This command should display the help information for TreeSize's CLI, showing all available options and parameters.
Why this step is important: Confirming the CLI tool works properly prevents errors later in the process and ensures you have access to all features.
Step 3: Create a Basic Disk Analysis Report
Run a simple disk analysis to get an overview of your system's disk usage:
TreeSizeCmd.exe /scan /path:C:\ /report:disk_usage.txt
This command scans the C: drive and generates a report in the specified text file.
Why this step is important: This basic scan gives you a starting point for understanding disk space distribution and can be used for future comparisons.
Step 4: Generate Detailed Folder Analysis
For more granular analysis, create a detailed report of specific directories:
TreeSizeCmd.exe /scan /path:C:\Users\ /report:users_folder_analysis.xml /format:xml
This command scans the Users directory and outputs an XML-formatted report.
Why this step is important: XML reports are more detailed and can be parsed programmatically, making them ideal for automated analysis or integration with other tools.
Step 5: Set Up Automated Analysis Script
Create a batch script to automate regular disk analysis:
@echo off
echo Starting disk analysis...
TreeSizeCmd.exe /scan /path:C:\ /report:analysis_%date%.txt
echo Analysis complete.
pause
Save this as disk_analysis.bat in your desired location.
Why this step is important: Automating analysis saves time and ensures consistent monitoring of disk usage over time.
Step 6: Parse and Analyze Report Data
Use PowerShell to parse the generated report:
$report = Get-Content "disk_usage.txt"
$report | Where-Object { $_ -match "^\s*\d+\s+.*MB" } | Sort-Object -Descending | Select-Object -First 10
This PowerShell command filters and sorts the report to show the top 10 largest items.
Why this step is important: Parsing the reports programmatically allows you to extract meaningful insights without manual analysis, which is particularly useful when dealing with subscription-restricted GUI features.
Step 7: Schedule Regular Analysis
Use Windows Task Scheduler to run your analysis automatically:
- Open Task Scheduler
- Create a new task
- Set the trigger to run weekly
- Set the action to run your batch script
Why this step is important: Regular automated analysis helps you stay informed about disk usage trends and can alert you to potential storage issues before they become critical.
Step 8: Export Results for External Analysis
Export your findings to formats compatible with other analysis tools:
TreeSizeCmd.exe /scan /path:C:\ /report:export.csv /format:csv
This creates a CSV file that can be opened in Excel or imported into data analysis tools.
Why this step is important: Exporting to CSV allows you to leverage external analysis tools and create visualizations that might not be available in TreeSize's GUI.
Summary
This tutorial demonstrated how to use TreeSize's command-line interface to analyze disk space usage without relying on its potentially subscription-restricted GUI. By following these steps, you can maintain your disk analysis capabilities even when software licensing changes. The CLI approach provides flexibility, automation capabilities, and access to detailed reports that can be parsed and analyzed programmatically. This knowledge is particularly valuable when software companies shift from perpetual licenses to subscription models, as it ensures you retain access to essential tools for system administration and optimization.
