Can I synchronize two folders with TreeSize?

No, TreeSize cannot synchronize folders.

I want to export my scan results into an Excel spread sheet. The whole process of scan invoking and exporting should be automatic. How can I do this?

You can use command line paramaters to start a scan and automatically generate an Excel report. For example: You want to scan the drive C:\ and your installation directory of TreeSize is
"C:\Programs\JAMSoftware\TreeSize Professional\TreeSize.exe"
Your directory for your reports is
"D:\My Company\Reports\TREESIZE\sheet1.xlsx",
with "sheet1.xlsx" as your sheet for reports. In this case, the full command line would look like this: "C:\Programs\JAMSoftware\TreeSize Professional\TreeSize.exe" /EXCEL "D:\MyCompany\Reports\TREESIZE\sheet1.xlsx" "C:\" Paths containing directory names with spaces must be embraced by double quotes, so it is a consistent and careful habit, to double-quote all paths, to avoid problems. Instead of retyping the command line every time you want to scan, you can save it into a .bat-file and start it by double-clicking.

How can I make TreeSize to export data to Excel in the same spreadsheet (same file)?

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.

Can I create a report that shows the difference between two folders?

You can compare a scan to another folder using "Scan > Compare with path". This will show the size differences on folder level between the path that was scanned, and the one that was selected for comparison.

When looking at the File Ages tab, how can the files within each bar be displayed? How can the time periods on the Files Ages tab be customized?

You can use the right click menu and select "Show files of this date interval" to open the file search and automatically list allf files of the selected interval. The intervals and type of date (last change, last access or creation date) of the file ages can be customized in the options dialog (Tools / Options / File Ages).

How can i restore files i accidentally deleted

Unless instructed otherwise TreeSize deletes all files to the Windows using the same mechanism as the Windows Explorer. That means, if according to your settings files get deleted to the recycle bin, they can be recovered from there.

TreeSize works great in finding thousands of duplicate files, but how can I select the subset I want to delete other than one at a time?

If you want to keep the newest file of every group only, you can select "Check all but newest" from the "Duplicate Files" tab in the ribbon menu. In addition to that, the dropdown selection offers a large variety of additonal options to custom select files. If you want to choose for each group of files individually which one to preserve, you obviously need to do this one by one.

Can Treesize Professional search by groups of machines? I want to be able to search multiple unc paths without adding every one of them individually.

You can search all shares of a remote machine by entering the unc path of the machine only, e.g \\machinename. You can search all shares of all members of a domain by entering the UNC path of the domain, e.g. \\domainnane.

I want to run a report that will give me a listing of the number of files accessed between a certain date and the total size of the files. Can I customize the "Age of files" view to be more granular?

You can adjust the intervals used for the "age of files" statistics under: Tools > Options > Age of Files
The custom search type of the TreeSize File Search, which can be opened through the Windows Start or the TreeSize Tools menu, is also very suitable to get a list of files accessed or not accessed in a certain time range.

After a custom search for files of a specific owner, how can I easily select all files and change their ownership?

You can select all files via the usual keyboard shortcut Ctrl-A, or via "Home > Select all" in the ribbon menu. Changing the file owner for all selected files can be done by clicking "Change file owner" in the right click menu of the result list.

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.

Is it possible to schedule a scan for duplicate files on a network?

Yes. Open the TreeSize Professional File search using the Windows Start menu or the TreeSize Tools menu, activate only the duplicate file search, add the network paths in the "Scan paths" panel and start the scan.
