one drive

I just brought a laptop for convenience when I travel away from home. File synchronization is handy however what isn't and is rather frustrating is the fact that One Drive spits out everything I have on my Desktop PC onto the laptop. Its one thing when the Monitor is 32" and the laptop is 15.6"...

i basically need to make a copy of all the data on one drive to gdrive. I use good sync currently but it is very,very,very slow. I tried cyberduck but it crashes randomly and is not reliable at all. The data I have to transfer is around 4.5tb. I have tried mover but the task just gets queued...
