We have most of our drive space empty, In this project we ask user for permission to store data in their drive, uploaded files are sent to main server then it asks for permission from admin and upload it in parts to admin(s) drive, other users can download it now, admin can distribute it in network of user drive or on multiple request on single drive it will automatically distribute it, large files can be stored this way, like in torrent it uses client as a server to drop the load on main server similarly we are using google drive as they are available 24X7 and are faster, we are dividing the file so even if some user decide to delete it, no large data is lost.
