To bring up the Report options panel, use the
view options command, and select the Reports tab.
The Reports tab of the Options panel allows the reports generated in the Report panel to be customized.
The Show Size As option selects whether the file or folder sizes shown in the reports are the actual sizes of the files or folders, or whether they are the amount of disk space used. Click here to find out why these numbers are usually different.
The Sort Order option selects whether the items in the reports are sorted by size (largest first) or alphabetically by filename.
If the Show Modified Time in Duplicates Report box is checked, then an extra column will be included in the duplicates report that shows the modified time for each file.
