scala play framework file upload error - scala

Question

I am using this tutorial to upload a file in my play framework application. I am using the exact same code but I get following error.
[IOException: Path(/Users/hrishikeshparanjape/Desktop) exists but replace parameter is false]
Following is my code:
def upload = Action(parse.multipartFormData) { request =>
request.body.file("picture").map { picture =>
import java.io.File
val filename = picture.filename
val contentType = picture.contentType
picture.ref.moveTo(new File("/Users/hrishikeshparanjape/Desktop/"))
Ok("File uploaded")
}.getOrElse {
Redirect(routes.Application.index).flashing(
"error" -> "Missing file"
)
}
}
I am stuck here please help.

Looks like you need to specify the complete file name for moveTo
picture.ref.moveTo(new File(
"/Users/hrishikeshparanjape/Desktop/" + picture.filename))
