yes you can , but MegaSync is just better in terms of using and is more comfortable To use, also it gives the best speed u could get downloading a mega File/Folder,
i am saying this out of experience , as i have downloaded A sum total of 60 - 70 GB data using MegaSync , as of Today.
Rest is upon u.
I am using PC, and Megasync app.
I have imported a mega link using mobile
now when its comes to download, i tried to download a folder directly from that link.
It started downloading the files, however after sometime it stopped and showed that i have to upgrade to get more bandwidth.
ok,
then u can use megadownloader, but i suggested mega sync because i downloaded a 40GB Folder (IIT JEE MAINS & ADVANCED - PHYSICS Collection Class 11&12th [NV Sir - Etoos India]) using mega sync over a time period of about 10 days, there was no problem.
but it was about 2 years ago , so maybe something is changed with mega sync.
