For example:
*\Main Folder\Folder 1\Sub-folder 1\Sub-folder 1.1
*\Main Folder\Folder 2\Sub-folder 2\Sub-folder 2.1\Sub-folder 2.1.1
It will be two different groups because it divides it all the way down to the last sub-folder.
How do I make it group by, in this case, only the folder after the "Main Folder" and divide it based on that, regardless of the sub-folders under it?
In the screenshot below, how could I make the files group only to the U:\_GIS_ folder level?
