Apple PowerBook File Assistant - Manual (Page 21)

The way the PowerBook File Assistant updates files in a linked pair depends
on what kinds of changes are made. There are three kinds of changes:
m modifying the file or folder
m deleting the file or folder, or moving it to another place on the disk
m replacing the file with another file with the same name
When the PowerBook File Assistant notices these changes, it does the
following:
If the left file is And the right file is This is what happens
Changed Unchanged Right file is updated.
Unchanged Changed In a two-way link, the left file is updated.
In a left-to-right link, nothing happens.
Unchanged Deleted In a two-way link, you get a message
asking you if you want to delete the left file.
In a left-to-right link, the right file is updated.
Deleted Unchanged You get a message asking if you
want to delete the right file.
There are two ways the PowerBook File Assistant synchronizes
files—manually and automatically. You set whether you want manual
synchronization or automatic synchronization for each pair when you link the
files or folders.
