Scala - remove jpg from folder

Question

I am looking for an elegant way to delete all files in a folder with a .jpg extension

I have the following to count the common jpg files in a folder:

Option(new File(path).list).map(_.filter(_.endsWith(".jpg")).size).getOrElse(0)

Thanks in advance, any help is greatly appreciated :)

for {
  files <- Option(new File(path).listFiles)
  file <- files if file.getName.endsWith(".jpg")
} file.delete()
