eliminar imagenes de la carpeta archivo

Hey @irept27 
Are you refering to your "Library"?

If you are, then hold shift and select the "images" that you are looking to delete.

In Firefly "File Folder", click on one image and a box in the left handside will appear. 
I suggest choosing an image from the left hand side and work your way to the right. Hold the "shift" key and choose an image further way. Sometimes you have to double click. 

Press the "Right" click and you should have a menu to choose to delete selected images.

Cheers
