Can you use GPSResults to combine files or if not is there a program you can, if so what is it.
It is mac compatible if you run a Parallels virtual machine like me 
Otherwise GPSActionReplay should let you do it.
OPH finally got home from work to give it a try, worked thanks for the tech support
No probs guyz!
Mike George (K888) GTC Team Captain for Team East wrote a superb in depth analysis on gps devices, linked below. Page 18 of 36 
Para "After Sailing" describes how sbn files can be combined at the dos command prompt in windows, prior to loading into one of the track analysis programs.
I'm not sure how many files can be combined in GPSR, only tried two files myself.
Mikes' method described in his manual would allow for the combining of multiple files, and multiples of combined files.
