Even in the times of cheap terabytes, a final truth remains: Sooner or later every hard disk will near capacity. But there is help! TreeSize Free tells you where precious disk space has gone.

The freeware can be started from the context menu of a folder or drive and shows you the size of this folder, including its subfolders in an Explorer-like fashion. Large folders can be identified at a glance thanks to the gradient bar displayed in the background. All scan results can be drilled down to file level and filters, e.g. for files of a certain type, can be applied.

It scans network drives and locally synchronized cloud shares (except on Windows servers and within a Windows domain) - just like TreeSize Personal!

The column view presents more detailed information for each file and folder. Here you will find the size or number of files as well as the last access date and the owner (and other useful facts).

Scan results can be broken down with the flexible filter feature. You can use the filters, for example, to find files of a certain type, such as temporary files, text files, or images, and use this information to clean up your hard disks.

It works on the MFT (Master File Table) and reaches extremely high scan speeds. Scanning operations run in a thread, so you will see results almost instantly while TreeSize Free is working in the background. The Explorer context menu and drag & drop operations are supported within the application.

TreeSize Free can display the NTFS compression rate and apply the NTFS compression to directory branches.

Startup Tree Size Free as an Administrator to calculate the size of all folders - even directories for which you do not have access permission. Since the content of the files will not be read automatically during this procedure, Windows security and data privacy remain guaranteed.

Note: Limited functionality in the unregistered version.

What's new in this version:

- The setting that allows large folders and files to be marked in bold can be correctly deactivated again
- The column width in PDF exports has been optimized. It is now comparable to the respective width in the user interface, regardless of the scaling of the monitor.
- A bug that could cause the user interface to freeze in rare cases has been fixed
- The use of TreeSize Free on a Windows server is no longer supported. We recommend TreeSize Professional
