What's New in This Release: [ read full changelog ]

· All lists now provide a new button in their toolbar that allows to save their contents to an Excel file.
· Added possibility to export the tree map and the file ages chart in the "Schedule TreeSize Task" dialog.
· Here a new function "Save to Batch File" has also been added to the context menu of the text field containing the full command line.
· Retrieving the file version of EXE, DLL and similar binary files no longer changes their last access date.
· The context sensitive help via F1 key now also works correctly under Windows Vista.
· File Search: It is now possible to search for files whose path is longer than a certain number of characters.
· This allows to find paths longer than 255 characters which make problems e.g. in the Windows Explorer.
· File Search: A selected "Since" interval on the "Date" tab of the Custom File Search is now saved for the next start and to XML files (File > Save Search Options). Previously it was only saved implicitly as lower and upper border of the date interval.
· Bugfix: The "Since" date intervals were not working as expected if the negated date filter "Not Changed", "Not Access" or "Not Created" were selected.
· Bugfix: The date picker controls of the Custom File Search did not always report the state of their integrated checkbox correctly. This could lead to files missing in the search results.
