@julian Please add this function
I'm writing something and join this picture
![0_1522594272890_MONO-INC.jpg](https://i.imgur.com/4jEmDgk.jpg). A second later i decide to change it. So i delete it from my post and change it by another. The first picture always exist on
public/upload/files and can not be removed from the server. How to delete it and others ? i would remove files that are not used by nodebb.
