TreeSize

1. Installation

TreeSize is installed on Windows systems (Windows 10 Version 1809, Server 2016 Version 1607, or newer). The installation process is straightforward and guided by a setup wizard. It automatically installs any required components, such as the .Net Framework 4.8, if they are missing. For enterprise environments, it also supports silent installation via command line for automated deployment.

2. First Run and Configuration

Upon first launch, TreeSize offers a simple mode and a setup wizard that helps new users quickly start scanning drives. This wizard guides users through selecting drives or folders to scan and shows initial results such as the largest files or file age distribution. This makes it easy for users to get immediate value without complex configuration.

3. Scanning and Analysis

Users select any drive or folder to scan. TreeSize performs a fast analysis of disk usage, presenting a real-time folder tree sorted by size, along with charts such as pie and bar charts. It provides detailed insights into large files, old files, and file types consuming the most space, enabling targeted cleanup efforts.

4. Cleanup and Reporting

After scanning, users can delete unnecessary files directly within the program. TreeSize also supports exporting detailed reports in various formats, including HTML, XML, and PDF. For professional use, it allows scheduling scans and automated reporting to monitor storage usage over time.

• Configurable Scan Settings: You can define filters to include or exclude specific files or folders during scans, adjust scan depth, and customize how the software analyzes storage. This helps focus on relevant data and avoid unnecessary scanning.

• Customizable Views and Reports: The interface allows customization of displayed columns, their order, and grouping by file types or other criteria. Reports can be generated in multiple formats such as Excel, PDF, HTML, CSV, XML, or plain text, enabling businesses to tailor outputs to their needs.

• Scheduled and Automated Scans: The professional version supports scheduling scans and automating cleanup tasks, which helps integrate disk space management into regular maintenance routines.

• Regular Updates: TreeSize releases updates frequently-often monthly or even more regularly-addressing bugs, adding features, and improving performance and security.

• Automatic and Manual Updates: Users can update TreeSize directly from within the application, avoiding the need to manually download and install new versions.

• Offline Installer Availability: For environments with restricted internet access, offline installers are provided via the customer area, allowing manual update deployment.

• Update Management via Administrative Templates: Large organizations can control update behavior and user interface modes centrally through group policy administrative templates.

• Change Logs and Release Notes: Detailed release notes accompany updates, describing new features, bug fixes, and security improvements, helping users stay informed about changes.

• Data Ownership: TreeSize is an on-premises software solution, meaning all data scanned and analyzed remains fully under the control and ownership of the user or organization. The software does not upload or transfer your data to external servers or cloud services, ensuring that your data stays local and private.

• Data Portability: TreeSize allows users to export all scan results and reports in multiple standard formats such as Excel, XML, HTML, CSV, and plain text. This facilitates easy portability of your data for further analysis, integration with other tools, or archival purposes. Users have full access to their data and can move or archive it as needed without restrictions.

• Privacy and Retention: Personal data collected by the company (e.g., for account or licensing purposes) is retained only as long as necessary to fulfill legal obligations or service requirements. Usage data collected automatically is also retained for limited periods, primarily for improving service security and functionality.

• Subscription-Based Licensing: TreeSize offers subscription plans (Personal and Professional) that can be adjusted based on the number of users or licenses required. This flexibility allows organizations to scale their usage up or down as needs evolve.

• Flexible Deployment: TreeSize supports deployment in various environments, including network drives and servers, which helps scale the tool’s reach across an organization’s infrastructure.

• License Management: Licensing is managed centrally, and organizations can adjust the number of licenses or switch between plans (e.g., from Personal to Professional) to accommodate changing business needs.

• Trial and Evaluation: The availability of a free trial allows organizations to test scalability before committing to a specific license tier.

• Subscription Duration and Renewal: TreeSize subscriptions are typically granted for one year. The subscription automatically renews for another year unless the user cancels before the renewal date.

• Right of Withdrawal: New customers have the right to withdraw from the contract within 14 days without providing a reason. This withdrawal period starts from the date the contract begins.

• Cancellation Notice: To avoid automatic renewal, users must provide notice of cancellation before the subscription renews. While specific notice periods may vary, it is generally recommended to give at least 30 days' notice prior to renewal.

• Renewal Process: If no cancellation is made, the contract renews automatically under the same or updated terms. Users may have the option to renegotiate terms before renewal, though renegotiation can affect renewal chances.

• Termination for Breach: The vendor may terminate the contract if the user breaches payment obligations or other material terms, typically after providing prior written notice and an opportunity to remedy the breach.

• Data Protection and Privacy: TreeSize complies with the General Data Protection Regulation (GDPR), ensuring that personal data is handled according to strict European privacy laws. The company’s servers related to licensing and updates are located in Germany, supporting compliance.

• Security Practices: The software is developed in secure environments with controlled access, version control, static code analysis, and manual code reviews to ensure software integrity and security.

• Data Handling: TreeSize operates entirely on the user’s local systems, meaning no scan data is sent to external servers or cloud services. This supports compliance with data sovereignty and privacy requirements.
