How can i change upload file field text

Hey!
i want to change the text "drop your file here" from uploadfile field in a contact form

how can i do this?

Simple way is to create a folder called languages/ and then in that folder create a file called en.yaml (or whatever is your primary language). Then in there simply put:

PLUGIN_FORM:
  DROPZONE_DEFAULT_MESSAGE: "Your new upload text..."

ok,
thanks for your reply!
