It is NOT undirectional. It works in BOTH directions depending
which file is "newest" - this is basic principle of file synchronization.
And as I wrote it does NOT differ from ANY other kind of file
(Word doc, spreadsheet, music files, pictures, etc). There is no magic,
AB files are just files. Even more, many files in AB are text files
that can not only be synchronized but even edited manually, so
actually flexibility is way bigger than for example in Word doc.
