TreeSize 1 is a powerful and versatile disk space manager for Windows PCs and servers. It identifies space hogs and enables you to easily deduplicate content and reclaim valuable disk space. TreeSize will scan local and network drives on Windows, Linux, Unix (via SSH), Amazon S3 cloud object store as well as FTP, WebDAV, or SharePoint servers and can even access mobile devices such as smartphones.

The software scans selected folders or entire drives and shows the size of all directories and subfolders – right down to the file level. Clear charts help you keep track of disk space usage.

Find Space Hogs

Use the integrated TreeSize File Search to track down redundant, temporary, large or old files and export, move, delete, or archive them to a ZIP file. A user-defined file search allows to search accorrding to any criteria. All results can be exported in a variety of formats.

Familiar User Interface

The application offers an intuitive Ribbon user interface modelled after the Windows Explorer. TreeSize fully supports the Explorer context menu, facilitating easy integration in the Windows workflow.

Graphical Visualizations

TreeSize displays the allocation of disk space on your hard disk in fully configurable treemaps as well as bar and pie charts. Bar charts and pie charts visualize the size and occupied space of all subfolders of the currently selected folder. Treemaps offer even more insight: in addition to the size values, they present the hierarchical structure of a file system – even across directory levels. Drag and Drop operations are supported within the TreeSize treemap view.

Detailed Statistics

TreeSize provides a list of detailed information on subfolders and files of the selected folder (e.g. size, allocated disk space, percent of parent folder, date of last access, last change date). In addition to listing the file types and folders occupying the greatest amount of disk space, TreeSize can generate a list of the 100 largest files, thus providing easy orientation. You can also monitor the disk space usage of individual user accounts on your computer or server.

Monitor Disk Space Development

Scan results can be saved to the XML format and compared with current scans. Snapshots – „photographs“ of the disk space usage at a certain point in time – offer an even faster comparison. Windows itself creates snapshots from time to time, enabling you (depending on your system settings) to load information on disk space usage saved before TreeSize was installed on your system. This is very useful if a hard disk has already reached capacity and disk space needs to be reclaimed without creating large reports.

Export and Print Scans

You can print all reports and graphs, send scan results via email, or save the collected data to different formats: XML, CSV, and TXT files as well as PDFs and fully expandable HTML or Excel files. All graphs can be saved as PNG, BMP, JPG, and GIF files. Scan tasks can also be planned via a comfortable interface.

Versatile File Search

The TreeSize File Search helps you find, delete, or archive redundant files. It enables you to search for the biggest or oldest files specifically and track down temporary files and internet files. The search criteria in the custom file search can be customized to perfectly match your requests. Files matching certain patterns are included in or excluded from scans effortlessly. It goes without saying that file content can be searched as well.

All filters integrated in the file search and the TreeSize main module support regular expressions and placeholders (wildcards). Your personal search settings can be saved and loaded again at a later date.

Specialized Duplicate Search

Duplicate files can be identified by various means. TreeSize uses a combination of file name, file size, and last change date or compares MD5 or SHA256 checksums. Since the file‘s content is used for the creation of those checksums, they guarantee exact results.

Optionally, TreeSize will not count NTFS hardlinks as duplicate files – although they are treated as separate files by Windows, they only occupy disk space once.

All duplicates can easily be deduplicated: either replace duplicate content with NTFS hardlinks or symbolic links or simply move or delete the unwanted files with the help of TreeSize.

Additional Features

Command line parameters facilitate automatic and time-controlled scan operations as well as report generation and – if desired – sending of scan results via email (comfortable user interface integrated). (Available in Professional Edition)

Multithreaded scans guarantee highest performance: each directory tree is scanned in several parallel operations.

TreeSize offers full NTFS support: file-based NTFS compression is supported, NTFS hardlinks and alternate data streams (ADS) are recognized.

File paths longer than 255 characters will be processed correctly.

Full network support: TreeSize scans an unlimited amount of machines in a network.
