A file echo is a network of boards that pass files along, the way message echoes pass messages. PBTic is the program that processes them.
When a file arrives from your uplink, it comes with a small description file ending in .TIC. PBTic reads it and puts the file in the right file area. PBToss starts PBTic for you; you do not run it by hand. It reads its settings from PBTIC.CFG.
