;This is a little snippet to use /filter to sort a list by filesize.
;This can help you if you have a list in a dialog, or a window that only has file sizes,
; or in an MDX ListView to list a the files by size when clicking on the size header.

;If you are using MDX, you need to use these lines to check if it's the Size header:
;Just replace "Dialog" with the Dialog name,and "ID" with the list's ID

; var %head = $gettok($did(Dialog,ID,1),3,32) ;This checks what header was clicked (Used only when the event was triggered by clicking on the header)
; tokenize 32 $remove($gettok($gettok($1,%head,9),1,4),$chr(32)) $remove($gettok($gettok($2,%head,9),1,4),$chr(32)) ; This will get the information in Header number %head

; For example, if you know that your Size header is the seconed header, just put 2 instead of %head

; Then to use the alias type this:
; /Filter -acio Dialog ID Dialog ID Sortbysize

; Or if you are using MDX ListView:
; /Filter -arcio 2-9999999 Dialog ID Dialog ID Sortbysize

; The command example will sort the List in the specified Dialog in the same list.
; That's why "Dialog ID" Appears twice: The output ID is the Input ID.
