"Selection Groups" is a feature used to filter and highlight a group of file extension(s) at once, excluding the rest of the file extension(s) that do not match the "Selection Group" filter list.
This feature is useful when you have to transfer huge amounts of files. Especially if the directories you are dealing with contain large amounts of particular file types, or you need to download only one file type in a folder.
You can access the Selection Groups feature by going to: View - Selection Groups.
