TreeSize Professional is a powerful disk management utility whose main aim is allowing you to know which files and folders take up the most of your disk space. The program thoroughly analyzes your disk(s) and offers you very detailed information about their contents in several practical ways like charts, detailed lists, and treemaps. Then, you can export them in various formats.
The same installer allows you to install the personal and the professional editions of the program, being the latter capable of analyzing even network drives and UNC paths. Likewise, when you run the program you are asked whether to run it in standard or in administrator modes. Of course, the second is the advisable option if you are an advanced user, as the standard mode won't be able to analyze some system and/or hidden folders. As soon as you run the program, you will see a pie chart showing you the disk space usage of each folder in your system partition (e.g. C:\), in a percentage format. Unfortunately, the quantity of elements, options and configurable parameters might be intimidating for beginners or even standard users.
The program is characterized by a ribbon user interface whose options vary depending on the view you select. The available views are Chart, Details, Extensions, Users, Age of files, Top 100 files, and History. The Chart view can be rotated among Pie chart, Bar chart and Treemap, all with the 3D effect enabled or disabled. As for the details view, it shows you a list of the files and folders of the selected disk/location, with a very detailed level of information. Anyway, whatever view you select, you always have a left panel where your files and folders are listed with background bars that show you their relative sizes. By the way, you can select whether to display the sizes in Gigabytes, Megabytes, Kilobytes, or simply let the program select the best unit for each case.
Besides allowing you to know the size and disk space usage of your files and folders at a glance, TreeSize Professional offers you many more additional functions. For example, you can use it to clean up your disk, use its File Search tool to locate duplicate files, create snapshots of your disk's current status for later comparison, defragment your disk(s) and schedule automatic system scans. Also, you can use it as a file manager, as you can easily copy, move or delete files among many other useful tools and features.
To cut a long story short, TreeSize Professional is a very comprehensive software tool that helps you manage and optimize your disk(s) space in several helpful ways. While the program might be a bit expensive for most users, I would say it is a must-have for system administrators and IT professionals. The program includes native editions for both 32-bit and 64-bit editions of MS Windows.
v6.0 [Sep 29, 2013]
- Faster scans: The well-proven and extremely fast search technology of UltraSearch working directly on the NTFS file system structures has been incorporated to increase the performance of TreeSize Professional scans and searches on local drives.
- 64 Bit: TreeSize is now available as native 64 bit application (Professional Edition only). When scanning very large file servers memory will no longer pose a restriction.
- Added an option allows making folders and [Files] items expandable and show single files in the directory tree.
Comparing / Trend Analysis
- Compare using historic snapshots: TreeSize Professional now facilitates comparing the current state of your local disk space with previous points in time using snapshots. No files need to be exported, even pre-existing snapshots that have been created by the system before TreeSize Professional was installed can be used for comparison. Additionally, TreeSize Professional offers an option to create a snapshot ("Tools > Create Snapshot").
- Toggle between size growth and current size: After performing a compare using an exported XML file or a snapshot you can now toggle between a comparison mode showing the size changes in all controls, and the mode showing the current values. In addition you can enable new columns ("Growth" and "% Growth") presenting the size increases and decreases in any of these modes on the "Details" tab. Those columns are not activated by default, but can be enabled using the context menu of the "Details" list header.
User Interface
- On Windows Vista / Server 2008 and higher, a ribbon-style user interface is now used. We decided to use the Windows Ribbon Framework to create the new user interface for TreeSize Professional. The Windows Ribbon Framework is part of the operating system in Windows Vista and later and so ensures optimal support and integration also in future Windows versions. It is also used by MS Paint, MS WordPad, MS Movie Maker and the Windows 8 Explorer. On Windows XP/2003 you will still see the classic user interface with a main menu bar.
- The "Options" dialog has been redesigned. Several new options especially for exporting have been added (see next section). A new checkbox "Expert mode" allows activating a mode that shows additional options that can be useful for experienced users.
- The include/exclude filter in the "Options" dialog has been revised. It offers matching by regular expression, exact match, filtering by owner and offers a preview of the impact of a filter in an Explorer-like view.
- Support for Windows Vista/7 style drag icons and drag hints has been added.
- You can now search the directory tree for a specific file or folder ("Scan > Directory Tree > Find" / Shift Ctrl F).
- The number of errors that occurred during a scan (e.g. access denied errors) is now shown in the status bar. Clicking it opens a dialog with detailed information regarding the errors.
Export Features
- The HTML export has been revised: When JavaScript is enabled, you will now see a dynamic view which allows expanding and collapsing each level of the folder structure. Subfolders are now properly indented. Folders are formatted as hyperlinks; clicking on them will open the folder.
- Email: Besides sending emails using your MAPI client it is now possible to send them through STMP as well. This is useful when sending emails from within scheduled tasks. The STMP setting can be configured at: "Tools > Options > Export > Email > Transport"
- You can now choose whether file information for single files should be included in Excel, HTML, Text and Printed export ("Tools > Options > Export > Exported elements").
- You can now choose whether an Excel export of the directory tree should support expandable / collapsible levels ("Tools > Options > Export > Excel > Expert Mode > Formatting").
- The type of information exported to an XML file can now be configured.
- The Personal Edition now supports the same export features (Excel, HTML, and Text files) as the Professional Edition.
File Search
- Custom Search: The pattern editor of the custom file search has been revised. It now supports regular expressions and also allows users to search in the file content.
- Custom Search: You can now search for both files and folders at the same time (tab "Size / Attributes").
- Custom Search: You can now decide whether your search filters shall filter by the number of NTFS hardlinks of a file. The new options "Ignore NTFS Hardlinks" and "Minimum Number of Hardlinks" are located on the "Other filters" tab.
- Duplicate Files: You can now define filters for the duplicate file search to include/exclude files whose file name, path or owner match certain patterns ("File Search > Duplicate Files > Filters"). Please note: Using a highly selective filter for the duplicate search will remarkably increase the performance of the search, since fewer files have to be compared.
