There are many programs to facilitate the handling of massive downloads, such as downloading large files.
First thing's first.
To choose one, the first is to use Firefox, it is more practical to find Addons compatible with the version that is installed ... and although a good amount of the mara resists change, I think that finally the Explorer will die. Also certain versions of Firefox come without the option to choose the folder where to save the downloads, I don't know why.
For this you only need to go to "tools / add-ons / get extensions / download management".
What I recommend
Well, there must be many, but I found this one and that seems to me to be good: it is Down them all!
After installing it (it will ask you to restart Firefox), when generating a download, an option to download it is added to the panel using the control panel Down them all, and the destination folder.
The panel seems very practical, you can choose the option to download or pause it. In case you want to download many files, you can leave downloading at night, to take advantage of the bandwidth at the time that only the geofumados stay overnight.
It is advisable to create the option that only one download is executed at a time, this is done in the lower right corner, "preferences / main", there it is configured so that only one simultaneous file can be downloaded.
After this, they activate all downloads (resume), so when one is finished, the other will continue ... thus ensuring better performance of the network and the download mirror.
Well, there they try it.
