How do I extract the name of the footage folder in Finder and pass it to a script?

I have a ScriptUI button that creates a comp of selected SWF files in my AE project panel and applies a few settings to them. You'll see how the comp is named "COMP_v01" but what I need is for the name to be taken from the name of the SWF folder in Finder. For example, the whole path might be "Volumes/Work/Project/MyGreatAnimation/Elephant/" with the 'Elephant' folder containing the SWFs. When I click the button I want the new comp to be named 'Elephant'.

         myPanel.grp.group2.swfSetup.onClick = function() {

            app.beginUndoGroup("SWF Setup")

            var myItems = app.project.selection;
            
             // Create comp
            var myComp = app.project.items.addComp("COMP_v01",1920,1080,1,60,24);

            // Put comp in the same folder as the selected footage
            myComp.parentFolder = myItems[0].parentFolder;

            // Create zAssets folder at comp location
            var myFolder = app.project.items.addFolder("zAssets");

            // Reverse for loop, so that the numerical layer names are listed correctly 00-99
            for (var i = myItems.length-1; i >= 0; i--) {

               var myItem = myItems[i];

               // Add selected footage
               myComp.layers.add(myItem);

               // Move footage to sub folder
               myFolder.parentFolder = myItems[0].parentFolder;
               myItems[i].parentFolder = myFolder;
               
               // Scale footage, and collapse tranformation
               //myComp.layer(1).transform.scale.setValue([200,200]);
               myComp.layer(1).collapseTransformation = true;
               
            }

            // Trim comp to duration of footage
            myComp.duration = myComp.layer(1).source.duration;

            // Deselects all items in the Project window
            var selectedItems = app.project.selection;
            for (var i = 0; i < selectedItems.length; i++)
               selectedItems[i].selected = false;

            // Selects the new comp
            myComp.selected = true;

            // Open comp
            myComp.openInViewer();
            
            app.endUndoGroup();

         }

For bonus points, I'd love it if the selected SWFs in the AE project panel could first be placed into a project panel folder named 'Elephants', before contiuing with the rest of the script.

I've taken this as far as I can right now, so any help is appreciated. Thanks!
