hello, How you guys are downloading huge files through mega. They provide only 50 GB storage and 35 GB expires after one month of signup.
Can you please help me? bypass the download limit.
First of all, we’re going to need two programs:

Psiphon VPN


If you already use Megadownloader check that you have version 1.7, if not, you can download it from the link. Psiphon will be responsible for allowing us to download beyond the limit, although if too much is abused, it can fail a few times, but just don’t exaggerate (10 GB per hour, for example).


The first thing to do is to stop all downloads (square button), then open the Psiphon and connect. Once connected will open a window in the browser, which we could close without problem, but the Psiphon is left open.


When connecting we will go to our Megadownloader with the downloads entered into the program (As a recommendation to do it with 10 downloads to take advantage of it)


Then we start all downloads and when we see “Downloading” with 0.00 KB, go to the Psiphon and hit the “Disconnect” button.


Once the Psiphon is disconnected, we wait a few seconds, and the mega downloader should have resumed the downloads entered. This is a Freeware it won’t charge anything.


I recommend that if we’re going to download a lot of files, let’s upload the number of downloads, preferably covering all of them to take advantage of the use of Psiphon, which we can generally use as much as we want. Besides, it is important to point out that this doesn’t always work, since what Psiphon allows is to extend a little more the download limit of the Mega itself, so in case it doesn’t work anymore, after having downloaded, we will have to wait a certain time, until the bandwidth of the Mega page allows us to download more.


Thank you so much for sharing this.
Please share the missing videos also.
I will help you with re uploading if the download link goes down.
I have 50 mbps connection with unlimited bandwidth
I am just new to this site and I am loving it!
