50GB limit I think (per day) for the downloader instead of using the web site.Well, I usually use Mega when the option is available since it provides the best download speed. And if needed I quickly start the downloader, let it do its work and close it. Just a small 'it's there when I need' piece of software.
And I think the download limit is not active when using the downloader. I remember a file with over 7GB I downloaded without a problem. Or some downloads that combined were over 10GB on this day. So either I had some different limit than 5GB or the program sidesteps it. Dunno.
Could be wrong, might also get this limit if you just create an account on mega.
