Modifying Date Information for Date Sorting

I have an SMB share sorted by date. I went into some old video folders and deleted some unneeded sample vids and meta files. That cleanup reordered those videos on my Infuse display. Apparently it’s sorting by date modified rather than date added. Is there anything I can do in infuse to fix the sort order? If not is there anything I can do in Windows 7 to adjust the date attributes of those folders?

Follow up question… Is there anyway to get my empty folders either off from the display, or at least at the bottom of the display?
