Section 10 of the PLC 5 manual has the instructions for navigating sub directories and downloading txt files. It looks pretty straight forward, but if you need help let me know, i'll see if i can talk you thru it..

A)[/] moves up one level ( or maybe back to root, i forget which)
B)Type the name of the sub directory and hit [enter]
C)The softkeys should allow you to perform the standard [source/target] functions..
