Does Treesize Professional allow to search for files or folders to that a certain user has access to?

We are sorry, this is currently not possible. What you can do is perform a full export of the directory tree in the TreeSize main module, or of a result list of the TreeSize File Search, to Excel, and then use Excel Auto-Filter feature to filter the files in question.

TreeSize Professional shows the error ".NET Framework not installed - This application requires a higher version of .NET Framework to work properly." on startup and then terminates.

TreeSize Professional requires version 4.0 of the .NET Framework to work properly. Please make sure that the current .NET version is installed. During its installation TreeSize Professional checks the available .NET version. If necessary, TreeSize will update the framework automatically.

TreeSize Professional shows the error "Assembly not found - A .NET assembly could not be loaded." on startup and then terminates.

TreeSize Professional requires both the "Jam.Interop.dll" and "ChartAssembly.dll" libraries in addition to its .exe file to work properly. Please reinstall TreeSize. This will make sure that the two files are copied to the correct directory.

Does TreeSize use Gigabyte or Gibibyte?

TreeSize shows its formatted sizes in Mebi-, Gibi-, and Tebibyte, even though we are using the more "common" identifier Megabyte (MB), Gigabyte (GB), and Terabyte (TB) in the software. We decided to do it this way to prevent user confusion, because nowadays it is quite common to talk about e.g. Terabyte but actually meaning Tebibyte.

I want to open scan results that I have saved to an XML file. Is there a way to do this directly from windows explorer, without having to open TreeSize first and then use the menu to import the scan?

This can be achieved by creating a new entry in the "send to" context menu in windows:

1. Open the folder "%APPDATA%\Microsoft\Windows\SendTo".
2. Create a shortcut to your TreeSize.exe.
3. Open the properties of the new shortcut.
4. Under "Target" append the command line option "/OPEN".
5. Click "Ok".

In windows explorer, you can now right click on any XML file that you have previously exported to save your scan results and use "Send To" -> "TreeSize Professional".

Why can I not see any network drives within TreeSize?

Since Windows Vista and later, Microsoft enforces more strict security rules on the operating system. One side effect of this is that you may not see your mapped network drives anymore (Windows 8 and later), or they appear disconnected (typically in Windows Vista and 7) in allapplicationsthat run with administrator privileges.

This is because Windows uses different user environments for non-elevated and elevated processes. There are some workarounds to gain access to those network drives anyway:

  • Do not run TreeSize as administrator unless it is truly needed.
  • Manually enter the UNC path (e.g. "\\server\share") for the network drive into the path drop-down list and press enter.
  • Use the "Map network drive" or "Add drive or UNC path" dialog from the Drive List menu bar.
  • Enable "Linked Connections" as described here:

After scanning a share with TreeSize Professional I want to compare this scan with existing snapshots. After clicking the "Compare with Snapshot" button I retrieve an empty list of snapshots and the message "No snapshots available for this scan".

Either no snapshots are existing or not all necessary services are running on the destination system.
You can verify the latter one as follows: right-click on the destination directory in Windows Explorer, open the properties page and select the "Previous Versions" tab. 
If no snapshots are listed there, TreeSize itself cannot display any entries. If you see entries there, not all services required for the comparison were running. 
These services have now been started implicitly by opening the "Previous Versions" dialog. If you execute "Compare with snapshot" again, you should see the correct results.

I've noticed that the "Last Access" date is not updated, it is much older than the "Last change" date. What is the reason for this?

The last access date of a file is maintained by Windows. Since Windows Vista/Server 2008, Microsoft disabled the automatic update for the "Last access" date by default to improve system performance on NTFS formatteddrives. Because of this, the date won't be updated anymore if a file content is changed for example. That is also the reason why the last access date isn't a good indicator anymore for recent usage of a file.

For more information on these topics, please refer to the following MSDN articles:

I'm using the following batch script to start TreeSize scans with paths that are defined in a text file. TreeSize however doesn't produce the report!

FOR /F %%p IN (Paths.txt) DO START /WAIT "C:\Program Files\JAM Software\TreeSize Professional\TreeSize.exe" /EXCEL "report.xls" "%%p"

This is a common mistake when using the START command in batch files. The START command will interpret the first quoted string after the command as a title for the new command prompt instance. As the path to the TreeSize executable is quoted here, this will be the title for the cmd instance. Of course, the batch script won't work this way.

To be able to use quoted paths, you will have to pass a dummy title after the START command first. The following example script will work as expected:

FOR /F %%p IN (Paths.txt) DO START /WAIT "DummyTitle" "C:\Program Files\JAM Software\TreeSize Professional\TreeSize.exe" /EXCEL "report.xls" "%%p"

I did not notice when I bought the package that it was TreeSize Personal. What is the difference between the the Personal and the Professional version? Can I upgrade?

Please refer to our comparison table for further information on the differences between TreeSize Personal and Professional. You can purchase an upgrade to TreeSize Professional in your customer area.

If the NTFS deduplication (available since Windows Server 2012) is enabled, TreeSize displays some strange values for the size of files and folders. A lot of files have a size of "0 Byte" while a folder called "System Volume Information" requires a huge amount of disk space. What is the reason for this?

The NTFS deduplication segments files with fractionally equal content into so-called "chunks" which are moved into a the subfolder "System Volume Informaton\Dedup\ChunkStore\" (SVI) located on the corresponding NTFS partition. After the deduplication has been applied, the original files are replaced by a pointer to the corresponding chunk in the SVI directory. Two identical files will only require half of the disk space they occupied before after a NTFS deduplication. Since the original files now only contain a small pointer, the allocated disk space will be indicated by Windows with a much smaller value than before (for two identical files the occupied disk space would be indicated as "0 Byte"). To make TreeSize show the original file and folder sizes again, simply switch the view mode from "Allocated Space" to "Size". The "allocated size" shown in TreeSize is the disk space you would obtain by deleting the corresponding file

I have just noticed that the line chart in the "History" tab of TreeSize has gone. What is the reason for this?

The line chart can only be shown if there was a scan of the same root folder performed at an earlier point in time. Furthermore, for a reasonable comparison the scans must have the same exlcude filters defined. Please note the the history is saved in each user's Application Data folder.
