Hey Alex,
I get internet thru my cell phone. It's usually really fast, until I try to download a large file. When I try to download a large file, the download will start....then all of a sudden my phone will disconnect. And with Windows download...it will not resume where the download left off. It has to start the download over again...which then will stop after a short amount of time.
With a download manager....you can resume a download from where it left off...which is what I have to be able to do.
With most downloads, you can just drag the download link to the Free Download Manager icon and it will start the download with no problems. But with Calkwalk's download...it has to open a new browser window which totally messes up the download manager. It only download the website link....not the actual download.
