TreeSize Free v4.7.3 Review

As an available disk space analysis tool, TreeSize Free can help you quickly determine what content is using up all your hard drive storage space.

TreeSize Free uses a familiar folder interface to help you sort your computer's largest folders and files. It can search entire flash drives, internal hard drives, network drives, and external hard drives, or you can use it to analyze individual folders within these storage media.

This review is for TreeSize Free v4.7.3, released on May 7, 2024.

There isn't much I don't like about this program.

what we like
  • Several different sorting options are supported.

  • Can scan large files from internal and external hard drives.

  • Size units can be changed between GB, MB, and KB.

  • A portable version is available on the download page.

what we don't like
  • Supports Windows only.

  • The filtering feature isn't very helpful.

  • Program updates are infrequent.

  • Some features are only available to paid users.

  • Supports Windows 11, Windows 10 and Windows 8.1.
  • Displays the results in a file explorer-like structure.
  • The results can be changed to view the TreeMap version, giving you more insight into the size differences between subfolders.
  • Folders can be sorted by size, percentage of total space occupied under the same parent drive/folder relative to other times, last modified date, and the total number of folders/files they contain.
  • The largest folder under any parent folder is easily identified by the highlighting behind its text (this color can be changed in settings).
  • Values ​​can be displayed in KB, MB, or GB; the Auto Units option changes the units used for each file/folder based on its size for easier reading.
  • Filtering options can exclude or include results based on specific patterns; for example, you can include only ISO files to remove all other file types shown in the program.
  • The results can be printed.
  • The results can be made into PDF.
  • The interface can be changed to better support touch devices.
  • Context menu support means you can open TreeSize Free to any folder or drive via File Explorer.
  • You can open or delete any file or folder shown in the results.

I like TreeSize because, unlike File Explorer, you can easily tell which folders are larger than others, and which files within those folders are the largest and smallest. This is the core reason why you need a disk analyzer, so in that sense, this program does exactly what you expect.

However, some disk analyzers have additional features that make them different from TreeSize Free. Although the tree view provided here is useful, sometimes it's easier to understand the results if you have a different perspective. For example, other disk analyzers may list the file extensions that take up the most disk space, which can give you a quick idea of ​​the types of files you may want to avoid or store elsewhere to prevent hard drive clutter.

The ability to filter results in TreeSize is a pretty neat idea so that it's not cluttered with irrelevant information, but here it is: all results are still displayed. I mean, for example, even if you filter the results to show only ISO files, all folders without ISO images will still show up in the results, which doesn't seem to help much.

Whatever I don't like, I think it's more useful in determining which folders and files are taking up disk space than what's available in Windows. Plus, there's a portable version of the program, so you can use it without installing it and take it with you on a flash drive.

You can download TreeSize Free above, and also check out my review of WinDirStat, another good option you might prefer.
