There are difference in download managers
GetRight & Gozilla worked best in the USA & Canada
ReGet and DAP were basically favored in Europe
FlashGet (aka JetCar) and NetAnts were favored in the Orient
I never could get GetRight or Gozilla to work at the Oriental sites. They simply would never catch the download link no matter how many times I tried. I switched to FlashGet years ago after Oriental site after Oriental site so suggested.
ReGet and DAP proved to weak and clumsy to bother with.
It is my understanding that, as of now, FlashGet is the best download manager around. It works all over the world nowadays. No doubt it is the simpliest and easiest to use. One can quickly and simply change download folders on the fly
