If the search does not return any results, but te search filter have been set corretcly, this could be due to a missing file content reader for Microsoft Office files. The reason for the absence of these handlers is in most cases a non-existent Office installation. 

If you do not want to install Office on your system, Microsoft provides separate filter packs to install these file handlers. These can be downloaded here: https://www.microsoft.com/de-de/download/details.aspx?id=17062

Starting TreeSize from a command line (cmd.exe), you can use the pipe-notation to redirect output from the standard output stream (1) and standard error stream (2) to a file. E.g.:

TreeSize.exe /NOGUI C:\ 1>StdOut.txt 2>StdErr.txt

From the PowerShell, it's recommended to use the Start-Process command with matching parameters:

Start-Process -FilePath .\TreeSize.exe -ArgumentList "/NOGUI C:\" -RedirectStandardOutput ".\StdOut.txt" -RedirectStandardError ".\StdErr.txt"

Yes. TreeSize addresses drives formatted with ReFS using the api provided by Windows. There are no known issues or limitations.

The portable installation is intended for use on a USB stick and cannot simply be moved or copied.

On a virtual machine (VM) the normal licensing conditions apply, therefore the portable installation will not start there.

An exception are the unlimited site, nationwide or worldwide licenses as well as the consultant license: These can be started on any system of the customer without specifying the license key and also without installation.

UltraSearch is optimized for fast searching and finding and offers a simple interface with quick access to the most important search functions, such as folder or file search, exclusion filter, date filter or file type search. The program is intended for "quick searches on demand" and indexes the file information in the system memory for this purpose, for lightning-fast results.

The TreeSize file search is much more flexible and offers you additional search options such as a duplicate search or the search for any metadata. Predefined search settings let you find duplicate, temporary or very large files.
The TreeSize file search not only offers versatile search options, but also offer in addition to the main module a great way to clean up your hard drive.

The implementation of Azure File Sync is meant to be completely transparent for the end-user. Accessing a file usually looks exactly the same with or without Azure File Sync.

TreeSize should be able to scan the server, as usual.

TreeSize will try to work on the metadata of the files/folders, whenever possible. Accessing these metadata will usually not trigger any download in Azure File Sync.

TreeSize will also respect offline files (stubs) and try avoid to trigger a download. This requires the files to be marked with the offline attribute though, which depends on the actual implementation of the scanned system.

If you are in doubt about using TreeSize for your specific configuration, we would recommend to try it on a smaller folder first.

You have several possibilities to analyse this:

1. If you have previously exported a scan with TreeSize into an XML file, you can use this for comparison. To do this, use the function "Compare with saved scan" on the ribbon bar "Scan" after a scan of the drive. It is possible to automatize the creation of the XML files.

2. If shadow copies are activated on the drive, you can also use them for a comparison. To do this, use "Compare with Snapshot" on the "Scan" ribbon bar.

3. If you have an older backup of the drive and it is accessible via a path, you can make a comparison via "Compare with path".

4. Switch on the option "Only files with creation date within the last X days" under "Tools > Settings > Scan > Filter" and examine the drive. Only corresponding files are taken into account when determining the folder size.

5. If this method is not successful, existing files have probably increased in size. It is best to use the TreeSize file search to find files that exceed a certain size and have been changed recently.

Yes, a dark mode is available in the latest version of the software. You can activate the dark mode in the options at "View > Display". Please note that this feature requires Windows 10 build 1809 or later.

Starting TreeSize with the command line paramter /SCAN followed by the path of a text file will scan all path in the scan.

You may consider grouping together all those files in a single root node using "View > Group Scans". The same can be achieved by passing the command line paramter /GROUPSCANS

If you have problems accessing SharePoint via TreeSize please check the following points:

  1. Did you complete the app registration with the required API permissions?
  2. Does your user have the permission to search the requested page? (Please note that the role "SharePoint admin" does not automatically have the permission to search all pages)
  3. Has your user been assigned a valid Office 365 license?
  4. Make sure that you have entered a valid path. Does the path point to a page or a document library?


For instructions on how to register the app and an overview of the required permissions, see "Azure AD Registration" in the TreeSize manual.
