History rewind function allows you to view your inventory of volumes based on a selected date, or differences in inventory between selected dates.

Right click in the inventory window and select View → History Rewind

From the History Rewind window click the calendar icon in the drop down list to select the required date.

Volumes will be displayed, in volume-ID order by default, showing location on the selected date. Volumes that were not part of the inventory at that date, but are currently, will be displayed as Did not exist with a red flag icon.

Selected date may be changed by either selecting another date from the drop down list or by scrolling, forwards or backwards, with the arrow buttons at the top right of the window.
