The reason for this is usually that the task is running under a different user account than the TreeSize user interface and so finds other settings in the user profile. One possibility would be that either is running as Administrator while the other is not. 

You can ensure that the task uses the same settings for all users by exporting your current options from the UI via "Home > Options > Export" and using that file for your task as well. You can then use the TreeSize task scheduler dialog to modify an existing task and select "Use saved options" in combination with your exported options file.You can also manually modify the task via the Windows Task Scheduler and append the command line argument /OPTIONS <pathToOptionsFile>.

You can do this using the TreeSize File Search. One of the matching options there is "Permissions".

Our disk space manager for enterprise environments, SpaceObServer, has the ability to collect the permissions of a volume in its database and to apply filters on this data. This is much faster and more convenient.

TreeSize Professional requires version 4.7.2 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 requires a few libraries (DLLs), like "Jam.Interop.dll" or "ChartAssembly.dll", 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.

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.

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.

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"

Most trial/demo versions of our products support the activation with a valid license key and then unlock all the features of the full version.

Alternatively, you can always install the full version over the existing trial version, your settings from the trial version will be taken over unchanged.

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

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 exclude filters defined. With TreeSize v8 and later, you can skip this check and include all history data, regardles of the filters.

Please note the the history is saved in each user's Application Data folder.
