File with size 0
Is it possible to add a property to disable the check for file size > 0?
I want to show a error for the user when he selects a file with size 0. Because the actual behavior, of ignoring those files, may lead the user to think that it is not working and then try again.
Not directly. I don't want to add more options than necessary. You can still override fileSetup event (it's fired for every File in the dataTransfer) and either track zero-sized files and show them later using other means or set passed file's size to something other than 0 - e.g. -1. This is a dirty trick but lets you intermix empty files into result. Still, I would intercept the event instead of this way.
One of the other reasons why I want to specifically skip empty files is because this is the only way to track dropped directories (and the method is named eventFiles). I doubt browser will ever give a FIle with size = 0 in case of error unless it's really empty.
