David,

There is no way to do them all automatically, but you can do them one file
at a time with a command like:

  ogr2ogr -update -append myInDir\output\file_merge.shp  myInDir\abc.shp

You might need to add "-nln file_merge".

Of course, all the files have to have the same geometry type, and the same
attributes.

Let me know if this doesn't work.

Best regards,
