You could have downloaded GpsBabelWrapper 1.1 from our software library for free. This free program is an intellectual property of QuakeMap. The software lies within Home & Hobby Tools, more precisely Travel.
From the developer:
GPSBabelWrapper allows the rest of us to use rich functionality of GPSBabel via familiar Windows interface. It only builds a command line and calls GPSBabel. Hopefully it does it well enough so that you will be spared of typing on the DOS prompt. Tabs "Filters" and "Options" let you control data processing and define location of worker programs (GPSBabel and QuakeMap).
You may want to check out more software, such as Luxembourg3D, Disney Vacation Planner or Hotel Program, which might be related to GpsBabelWrapper.
