Since v8.1 there are two options to provide a default configuration:

  1. (Applies to all versions) Deploy a prepared TreeSize config file to "%AppData%\JAM Software\TreeSize\GlobalOptions.xml" of the user. If the user resets his copy of the options, the factory defaults will apply again.

    You can simply take it from any user's profile or use "Tools > Options > Export" in TreeSize to create such a file.
  2. (Available since v8.1) Deploy default configurations via the Windows Registry. You can configure and deploy them easily using administrative templates for the Group Policy Editor.
    More information and download options are available in the online manual.
    These settings will automatically take effect if the user starts TreeSize without having an options file already, or when resetting the options to default.

You may use our MSI installer to deploy the software to all users.

TreeSize is basically designed to visualize the current state of your storage, but it can also compare these results with previously exported ones to calculate the changes inbetween.

Starting with v9.0, you can use exports to the SQLite format for this. You can configure the task in the task scheduler, or run it from a command line. E.g. if you want to scan D:, compare it with an older scan, export the results of the comparison to HTML, and update the older scan, you could just call:

START /WAIT "TreeSize" Treesize.exe /COMPARE C:\Scan_D.SQLite /SQLITE "C:\Scan_D.SQLite" /HTML C:\Compared_D.html D:\

If you want to compare information on folder level only, you can also use the XML format. Doing so requires several steps though, combined in a batch script:

  1. Perform the scan of the path and export the scan to an XML file using the /XML command line parameter.
  2. Perform a compare of the scan from the step before with a previous one, using the command line parameter /COMPARE and export the results in an appropriate format
  3. Replace the XML file that represents an older scan with the current one, so that it can be used for the next run.

A batch file for drive D:\ could look like this:

START /WAIT "TreeSize" TreeSize.exe /XML "C:\New_D.xml" D:\
START /WAIT "TreeSize" TreeSize.exe /OPEN "C:\New_D.xml" /COMPARE "C:\Old_D.xml" /HTML "C:\Compared_D.html"
DEL "C:\Old_D.xml"
MOVE "C:\New_D.xml" "C:\Old_D.xml"

Our disk space manager SpaceObServer offers features like this out-of-the box, as it stores historic disk space data in a SQL database.

This problem is unfortunately caused by SharePoint itself.

SharePoint throttles the number of user actions for very large requests. This leads to the fact that TreeSize has to pause the scan after a certain number of calls for a short time (40 to 300 seconds) until new user requests are released.
If SharePoint interrupts the active scan due to too many calls, a message is written in the Windows Event Viewer that refers to the throttling.

To speed up or not unnecessarily slow down a scan, unused statistics (esp. the statistics on file owners and the option to 'Track advanced file system features') should be deactivated.

As an alternative, SpaceObServer may be interesting for you, as it also supports SharePoint scans. Due to the database used to persist the scan results, the data collecting process, and the reporting/analysis can be split up into two independed steps. Let the scan-service wait, instead of waiting yourself.

We discussed this behavior with several NAS vendors, who agreed that this is an issue with the SMB implementation of the specific NAS system.

Please check if their is an update available for your NAS and if it resolves this issue for you. If not, please contact the vendor of your NAS system and ask him to fix this behavior.

As a workaround in TreeSize, you can activate a legacy mode, where TreeSize would estimate the allocated values based on the sizes. To do so, please start TreeSize with parameter /UseLegacyEnumerator True

When deduplicating files, TreeSize replaces duplicate files by hard links, after which the physical data exists only once on the hard disk. There are however X links to this data. Each of these links is shown with the size of the physical data, this is why the Windows Explorer and by default also TreeSize shows the same size for these files and the folders they are included in.

If you take a look at the allocated space of the physical drive (e.g. in the "Drive List" in TreeSize or in the "Properties" of the drive in the Windows Explorer) you will notice the difference.

To get the correct physically allocated size of a folder, you need to look at the column "Allocated Space". In the TreeSize main application make sure that the option "Track NTFS alternate data streams and NTFS hardlinks" is turned on in the Options dialog.

Open the TreeSize File search using the Windows Start menu or the TreeSize Tools menu, add the network paths to the list of paths to Search, activate the Duplicate Search only and start the search. You may change the way TreeSize compares the files on the "Duplicate Files" tab.

Yes. And Long path can be explicitly searched for using the Advanced Search. Simply select the template "Files with long paths".

What you can do is using the Custom Search type of the TreeSize File Search. It allows to search the entire network or IPv4 address ranges for certain files, like *.pst. Simply specify \\*  or \\192.168.123.* as path to search. TreeSize will then enumerate all available PCs in e network or that IPv4 network segment and search their drives (or more exactly: their public and hidden shares) for the files matching the search criteria.

Yes, the TreeSize File Search can search, report and delete or move files over a certain age. You can select the template "Modified long time ago" in the custom search, to load a search configuration for old files. Check the files you want to delete and use the "Delete" button to delete or move them to the Recycle Bin. You can schedule this search and also automate a move or delete operation, by using the option "Tools > Schedule current search".

Unfortunately there is no short and easy answer to this question because usually one cannot know where a file came from and what it is used for. Generally temporary files and cache files of the internet browsers can nearly always be deleted safely. Besides deleting files, the File Search of the software offers you to move files to a different drive or to a compressed ZIP file (preserving the file system hierarchy) which can then be archived. That way files that are still needed can be easily restored, either manually or by using the restore script that the software is able to generate optionally.
