For example, I want to move app.css into the css folder I created. Drag-and-drop doesn't work. Right-click > Move doesn't seem to work either...it only opens the file name for renaming, instead.
You can use the "Rename" feature to move directories. So if I have a file example.png
that I want to move into the images directory, I just need to make the filename images/example.png
and a directory will automatically be created.
Hope that helps!
