aam i think a little bit of a clarification is req when talking about mega, the 5gb limit is not download/file it is download/time
so if you download 3 files each 2 gb size the last file 1gb will not be downloaded for another 5ish hours the same as the 8gb file on this one, however that does not mean that you can't download an 5gb+ from mega for free
how??
the download will resume after the 5ish hours download limit timer
i myself i downloaded this 8gb size without having a payed mega account or using workarounds the limit
i simply clicked download and in the mean time i can just play something else, or you can just start the download before going to sleep, by the time you wake up it's finished.
*note
there is also there app MEGAsync which i also use, this way i don't need a browser open for the download and never had any problem when resuming downloads after the timeout and it also lets me know how much time until i can resume the download, but it is up to you if you want to use it or not
