I would like to report on multiple mapped drives and have the locations reported on a single Excel worksheet. By default TreeSize will create a seperate sheet within the Excel file for each location. Is it possible to merge those sheets so I get a summarized report for all of the drives scanned?

Yes, this is possible by using the "Virtual Root Folder" feature of TreeSize. 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.

Is TreeSize capable of searching within a NetApp Filer?

Yes, TreeSize supports processing of NetApp filers, assumed they are mounted as a usual network drive.

Is TreeSize capable of accessing files and folders, which usually cannot be accessed, e.g. "C:\System Volume Information"?

Yes, but it may require that you start TreeSize as administrator.

Is it possible to run TreeSize as a different user?

To run TreeSize under a different user account, you can either start the application using the 'Run as' command which is available if you [Shift]+[Right-Click] the executable, or you can create a scheduled task. 

For the 'Run as' command you will have to enter the credentials each time the application shall be executed for that specific user, while for the scheduled task the credentials are only required once.

Does TreeSize track/count the depth of the scanned files and folders?

TreeSize tracks the directory and file depth and assigns it to a property called 'Dir Level'.You can view the level for any folder or file in the 'Details' view.To activate the column, right click on the column header of the details view and click 'Dir Level'. If you need to filter a scan result for a specific directory or file level, you can use the Excel export from TreeSize.Before exporting, make sure the 'Dir Level' column is activated in the options menu of TreeSize for Excel reports.To do this, go to Tools > Options >  Columns/Export and set the 'Visible Columns of' to 'Excel'.In the list below, look for the 'Dir Level' entry and check it. After scanning the system you can now use the 'File > Export > Export to Excel' button to create an Excel file that contains the scan data. With the filter features of Excel, you can now filter for any criteria.


Is TreeSize also available as portable version which can be installed and run from an USB stick?

The full version of TreeSize Professional can be installed on an USB stick and can be run from there. To install TreeSize Professional as "portable edition", install it normally on a PC, run TreeSize and click "Tools > Create portable edition".

How long would it take to scan a 1TB drive?

This highly depends on the performance of your hard disk, your PC, the number of files and folders and the settings. Just use our free an fully functional trial version and try for yourself. TreeSize scan using parallel threads and you won 't find a disk space manager that scans faster.

How can I see the file that has increased the space in the right hand window of a compare. Currently it only shows the folders and in the left hand window says FILE but when I click on the folder in the left hand window it does not list the files in the right hand window.

TreeSize stores data only on folder level, otherwise the mount of data would be too large.This is why it can 't display the the size increase of files.

We also offer another disk space manager called SpaceObServer which is designed for large servers and continuous reporting. It regularly collects the file system information using a background agent and stores it in a SQL database, including size development. It uses less RAM than TreeSize Pro and the reporting capabilities are faster and more flexible because it is built on a database and collects data on file level. SpaceObServer offers advanced scripting capabilities through OLE Automation. If you are interested, please visit:

I would like to know how within TreeSize you can work out what data was copied to another logical drive and when. For example D: drive has suddenly grown by 5GB, how do you determine what 5GB has been copied and when.

This kind of task is moresuitable to our hard disk manager SpaceObServer.By archiving the collecteddirectory information in a database, SpaceObServer enables your to get instantinformation about directory sizes, growth of allocated disc space (for each subdirectory) and to define filters (E.g.: Files create within the last X days)that can be applied immediately on the shown directory brunch.What you could do inTreeSize is to take a look at the "Age of Files" graphics (look forfiles create within the last few days), or compare the current scan with aformer stored XML report ("File > Compare With XML Report").

Does TreeSize work with long file names and path (i.e. >255)?

Yes,TreeSize will handle files with a full path longer than 255characters correctly. The integrated TreeSize File Search also offers a possibility to search all files with a full path longer than 255 characters.

I was doing a custom file search on my server. when I press the "save results " button and select my target file (local on the server), it takes very long to create the csv file. Is there any way to speed this up?

Do you have activated the "Owner" or the "Permissions" column? In Active Directory environments Windows can take a long time to query these values. To speed this up, the only option is to turn off these columns using the"View" menu if not needed.

We had a user who used treesize pro on a daily basis who has now left, we need to transfer his licence to another user/machine (un-install, re-install) but we wish to keep the history and continue to add to it maintain our trend analysis, can his history be copied to or imported into the fresh install

The values for the "History" tab are stored in an XML file named "scanhistory.xml" in the user's AppData folder ("C:\Users\<username>\AppData\Roaming\Jam Software\TreeSize").
Please copy this file to your new machine to keep your "History" values.
