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.

When using Excel as export format, TreeSize will create a spreadsheet with the current timestamp and save the data into this sheet.

If the same file is selected for another export, TreeSize will create another sheet and append it to the file, so you won't lose the data from the previous export.

In general, TreeSize can scan any systems that have a drive letter assigned in Windows. This typically applies to local drives, network shares, etc.

Most mobile devices will announce themselves as MTP (media transfer protocol) devices, which allows access via Windows Explorer without having an actual drive letter assigned. 

TreeSize supports the MTP protocol since v6.3 and should thus be able to analyse all data available with this protocol.

Please note that most operation systems do not grant access to all of the files on the device via MTP. Especially system files and internal data can not be scanned this way. User data (like pictures and videos) usually are accessible.

TreeSize is capable of scanning Distributed File System environments. It will follow the links to the target directories so you won't have to map single shares. It can be necessary to activate the option "Tools > Options > Scan > General > Follow external mount points and symbolic links".

Yes, this is possible by using the "Group scans" feature available on the "Scans" ribbon bar. Using this feature it is possible to group scans under a virtual root folder. This virtual root folder shows a summary of all scans that are part of this group. This way you can merge different scans together e.g. for printing or exporting. You can add or remove scanned paths individually from the virtual root folder using the context menu.

Yes, TreeSize supports processing of NetApp filers, assumed they are accessible as normal network drive.
