I have exactly the same question, and I can see there have been no replies to this tread.
I have moved from XYplorer to Multi Commander due to the lack of a XYplorer 64bit version.
I use it as replacement for the WinXP explorer which M$ totally screwed up in later Windows version, so I have a tree pane and a folder/file pane.
I have different sorting in different folders.
My download folder is sorted by date and should show files and folders seperately with files first, but I can only set it to folders first.
Please help.
