You have several possibilities to analyse this:

1. If you have previously exported a scan with TreeSize into an XML file, you can use this for comparison. To do this, use the function "Compare with saved scan" on the ribbon bar "Scan" after a scan of the drive. It is possible to automatize the creation of the XML files.

2. If shadow copies are activated on the drive, you can also use them for a comparison. To do this, use "Compare with Snapshot" on the "Scan" ribbon bar.

3. If you have an older backup of the drive and it is accessible via a path, you can make a comparison via "Compare with path".

4. Switch on the option "Only files with creation date within the last X days" under "Tools > Settings > Scan > Filter" and examine the drive. Only corresponding files are taken into account when determining the folder size.

5. If this method is not successful, existing files have probably increased in size. It is best to use the TreeSize file search to find files that exceed a certain size and have been changed recently.

Starting TreeSize with the command line paramter /SCAN followed by the path of a text file will scan all path in the scan.

You may consider grouping together all those files in a single root node using "View > Group Scans". The same can be achieved by passing the command line paramter /GROUPSCANS

If you have problems accessing SharePoint via TreeSize please check the following points:

1. Did you complete the app registration with the required API permissions?
2. Does your user have the permission to search the requested page? (Please note that the role "SharePoint admin" does not automatically have the permission to search all pages)
3. Has your user been assigned a valid Office 365 license?
4. Make sure that you have entered a valid path. Does the path point to a page or a document library?

For instructions on how to register the app and an overview of the required permissions, see "Azure AD Registration" in the TreeSize manual.

To get technical support for our product your maintenance period must be valid. Customers that are covered by maintenance are able to download all updates for free.  If there is a support case, we will typically ask our customers to install the latest version, as this may already fix the issue. If the latest version cannot be used for comprehensible reasons, we will also provide support for previous versions, but those will not receive any more updates.

You can look up the end of your support period in our customer area. There you can also renew it for a reduced price and will then get technical support and updates again.

In most cases, the reason for this is that Windows is not reporting the amount of hardlinks correctly.

In order to filter out files that were already deduplicated, TreeSize will ignore files that have more than one hard link. For files that are accessed via a network drive, however, there are cases where the amount of hard links is not returned correctly by the operating system, as stated in this article: https://knowledgebase.jam-software.com/7092

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.
