[Gpsbabel-misc] .gdb files

[C C. <cco...@rc...>]

Once again I need some help.  I'm trying to combine two .gdb file containing 
tracks and waypoints, so I'm venturing into the DOS command line for the 
first time in more than 10 years.

I'm using GPSBabel ver 1.2.7.

I issued the command  >gpsbabel -t -w -i gdb -f mex2005JK.gdb -f 
coppercanyon.gdb -o gdb -F big.gdb

The two input files are 228 kb and 284 kb respectively and the output file 
is 497 kb in size.

The two input files work fine in Mapsource ver 6.5, but the output file 
results in a message that says "big.gdb is not a valid Mapsource file and 
could not be opened."
