I just read about this feature. Do you want to make file name (with extension) swapped from left-to-right pattern to right-to-left pattern in Explorer? Algorithm: Select file. Press <F2> or select "Rename" in context menu. Press <Home> to undo the selection and place text cursor before the first letter of name. Bring context menu by the left mouse button or by the special key on the keyboard. In sub-menu of context menu item "Insert Unicode control character" chose item "RLO Start of the right-to-left override". Press <Enter> to confirm renaming. Have fun in reading the name of file. After such renaming file remains the same from OS point of view - its name just starts with inserted Unicode control character which can be seen in command prompt (command "dir"). File can be searched in Explorer by extension of by wildcard pattern. Easiest way to remove this control character is through command prompt Code: ren "[character]name_of_file.ext" "name_of_file.ext"
