The only problem is if you have the unlikely but not impossible situation where you have paths that contain no pages. Because of the known gotcha with LC and how it counts items when the last item is empty you may need to include and 'if' statement.
Try this, create a new Stack with a field and a button. Into the field load the following text: https://www.my.org/assets/general/february/ https://www.my.org/assets/general/march/ https://www.my.org/assets/general/april/2018.zip https://www.my.org/assets/general/may/2018.zip https://www.my.org/assets/general/june/2018.zip https://www.my.org/assets/general/july/2018.zip https://www.my.org/assets/general/july/2017.html https://www.my.org/assets/general/july/2016.text https://www.my.org/assets/general/july/2015.jpg https://www.my.org/assets/general/august/2018.zip https://www.my.org/assets/general/september/2018.zip https://www.my.org/assets/general/october/2018.zip https://www.my.org/assets/general/november/ https://www.my.org/assets/general/december/ Into the button load the following script (be careful of line breaks there are 16 lines of code): on mouseUp put fld 1 into tText set the itemDelimiter to "/" repeat for each line tLine in tText if (char -1 of tLine = "/") then --usual problem with dealing with empty last items put empty into tPath[tLine] else if (tPath[item 1 to -2 of tLine] = empty) then --initial entry put item -1 of tLine into tPath[item 1 to -2 of tLine] else --multiple entries put tPath[item 1 to -2 of tLine] & cr & item -1 of tLine into tPath[item 1 to -2 of tLine] end if end if end repeat breakpoint end mouseUp There is breakpoint at the end so the script will pause and you can inspect the variables. You'll see that an array is created with each unique path as a key and each page its element. In the case of 'july' you will see that four pages are all listed, one per line. From there it should open a world of possibilities to arrange, sort and sift through the paths.
