Loading and saving

ROX uses drag-and-drop for file operations. Users load files by dragging to your application directory. They import files by dragging into a document window. They save by dragging back to a filer window. See Edit for an example of this.
The traditional method of using a 'mini-filer' window is bad because:

The user must learn two interfaces (the application and the filer) which do the same thing -- navigate the filesystem.
Mini-filers either have too little functionality (eg, can't create a new directory, can't search for files) or have too much and are confusing.
It should be the user's choice which filer to use for all applications, not the application author's choice on a per-application basis.
Mini-filers invariably default to the wrong directory. In ROX, the user can have multiple filer windows open, drag to pinboard and panels and so on.
Drag-and-drop saving allows the user to save directly from one application into another.

When some data (not in a file) is dropped onto your application directory, ROX-Filer will ask you to load '-' and passes the data in on standard input. Make sure you support this!
Menu items names:

Save As... opens a savebox. Most programs only need to provide this. It is called Save As rather than Save to avoid confusion with Window's Save behaviour.
Quick Save saves directly using the current filename without opening a savebox. This is what many systems call Save, but to avoid confusing with
RISC OS we use a different name.
