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 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.
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.
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".
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: https://www.jam-software.com/knowledgebase/6898
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.
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:
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"
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 exlcude filters defined. 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.
You can also specify a "Default Export File", so you don't need to select a file, every time you want to export the data. This can be done either in the Options of TreeSize (Tools -> Options -> Columns/Export -> Excel Export -> Default Export File") or in the corresponding export dialog (File -> Export -> Export to Excel -> "Always use this filename and add a new sheet when exporting").
When the default file was defined, you can simply go to "File -> Export -> Export to Excel" and TreeSize will add the current scan data to its own Excel sheet, using the default export file.
