About external files

Trees whose root headline starts with @file, @auto or @edit create external files on your file system. Here are some example headlines:

@file myClass.py
@auto ../graphics/circles.cpp
@edit ~/.leo/.leoID.txt

As you can see, these nodes specify file names, which can be an absolute path or a path relative to the directory containing the Leo outline.

Collectively, nodes that create external files are known as @<file> nodes. Leo defines several other kinds of @<file> nodes, but this slideshow will not discuss them.
